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. 402-63-1, name is 1-(3-Fluorophenyl)ethanol, molecular formula is C8H9FO, 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. Recommanded Product: 402-63-1
Example 98 1-(3-Fluorophenyl)ethyl N-{4-[(6,7-dimethoxy-4-quinolyl)oxy]-2,3-dimethylphenyl}carbamate 4-[(6,7-Dimethoxy-4-quinolyl)oxy]-2,3-dimethylaniline (86 mg) was added to toluene/triethylamine = 10/1 (9 ml), and the mixture was heated under reflux to prepare a solution. A solution of triphosgene (150 mg) in methylene chloride was then added to the solution, and the mixture was heated under reflux for 15 min. Subsequently, 3-fluoro-alpha-methylbenzyl alcohol (70 mg) was added thereto, and the mixture was further stirred with heating under reflux for 2 hr. After the completion of the reaction, the reaction solution was allowed to cool to room temperature before distilled water was added thereto. The mixture was subjected to separatory extraction with chloroform, followed by washing with a 1 N aqueous hydrochloric acid solution and saturated brine. The washed solution was dried over sodium sulfate andwas concentrated. The residue was purified on a column using chloroform/methanol to give the title compound (89 mg, yield 64%). 1H-NMR (CDCl3, 400 MHz): 8.38 – 8.44 (1H, m), 8.13 (1H, s), 7.66 – 7.75 (1H, m), 7.64 (1H, s), 6.95 – 7.36 (6H, m), 6.51 (1H, d, J = 6.4 Hz), 5.87 (1H, q, J = 6.6 Hz), 4.15 (3H, s), 4.09 (3H, s), 2.25 (3H, s), 2.07 (3H, s) Mass spectrometry value (ESI-MS, m/z): 492 (M++1)
With the rapid development of chemical substances, we look forward to future research findings about 402-63-1.
