Application of 6329-73-3, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.6329-73-3, name is 1-(Benzo[d][1,3]dioxol-5-yl)ethanol, molecular formula is C9H10O3, molecular weight is 166.1739, as common compound, the synthetic route is as follows.

General procedure: In an oven dried Schlenk tube, were added alcohol 1 (69.0-199.5 mg, 0.5 mmol), CuI (10 mol%)and 1,10-Phenanthroline (20 mol%) and K3PO4 (2 mmol) followed by the addition of dioxane (2mL) at room temperature under open air atmosphere. The stirred reaction mixture was heated inan oil bath at 80 C for 7-48 h. Progress of the reaction was monitored by TLC till the reaction iscompleted. Then, the reaction mixture was cooled to room temperature, quenched with aqueousNH4Cl solution and then extracted with CH2Cl2 (3 10 mL). The organic layer was washed withsaturated NaCl solution, dried (Na2SO4), and filtered. Evaporation of the solvent under reducedpressure and purification of the crude material by silica gel column chromatography (petroleumether/ethyl acetate) furnished the aldehyde/ketone 2 (61-97%).

Statistics shows that 6329-73-3 is playing an increasingly important role. we look forward to future research findings about 1-(Benzo[d][1,3]dioxol-5-yl)ethanol.

Synthetic Route of 6329-73-3, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 6329-73-3, name is 1-(Benzo[d][1,3]dioxol-5-yl)ethanol, molecular formula is C9H10O3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

General procedure: To a stirred solution of alcohol (1 equiv) in dry DCM (10 to 20 mL), thionyl chloride (1 .7 to 3 equiv) was added slowly at 0 C. The reaction mixture was warmed to rt and was refluxed for 1 h. The reaction mixture was concentrated under vacuum and the resulting residue was diluted with DCM (20 to 50 mL). The DCM layer was washed with water (5 to 10 mL), brine solution (5 to 10 mL), dried over anhydrous Na2SO4 and concentrated under vacuum to give chloro compound.

According to the analysis of related databases, 6329-73-3, the application of this compound in the production field has become more and more popular.

Synthetic Route of 6329-73-3, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 6329-73-3 as follows.

Step 2; To a cold (ice water) suspension of sodium hydride (316 mg; 7.9 mmol) in anhydrous DMF (10 mL) is added a solution of the previous alcohol (1.31 gm; 7.9 mmol) in anhydrous DMF (5 mL) over 10 minutes. After allowing to room temperature over 30 minutes, this solution is added to a cold (ice water) stirred solution of 2,6-difluorobenzonitrile (1 gm; 7.2 mmol) in anhydrous DMF (15 mL), and allowed to room temperature overnight. The reaction mixture is poured into ice water with vigorous stirring and extracted with ethyl acetate. The organics are separated, washed with brine, dried over magnesium sulfate, and the solvent is removed to give 2.22 grams 2-(1-benzo[1,3]dioxol-5-yl-ethoxy)-6-fluorobenzonitrile.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,6329-73-3, its application will become more common.
