Synthetic Route of 13330-96-6, 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.13330-96-6, name is 4-(Dimethylamino)butan-1-ol, molecular formula is C6H15NO, molecular weight is 117.19, as common compound, the synthetic route is as follows.
General procedure: To a solution of 6-substituted pyridazinone 9 (0.5 mmol) in DMF (10 mL) was added Cs2CO3 (0.55 mmol). An appropriately substituted nitro benzyl chloride (0.52 mmol) was added and the resulting mixture was stirred at 40-50 C for 3 h, the solvent was removed under reduced pressure and the residue was dissolved in EtOAc (30 mL), which was then washed with brine (3 × 10 mL). The organic layer was dried over anhydrous Na2SO4 and concentrated in vacuo. The crude product, 2-nitrobenzyl-6-substituted-pyridazin-3(2H)-one (10), was used in the next step without further purification. To a solution of 10 in 95 % ethanol (50 mL) was added acetic acid (10 mmol) followed by slow addition of iron powder (2 mmol). The resulting mixture was stirred for 5 h at 100 C. The mixture was then filtered through celite and the filter cake was washed with 95 % ethanol (3 × 15 mL). The combined ethanol filtrates were evaporated in vacuo and the residue was re-dissolved in ethyl acetate (30 mL). The organic layer was washed with brine (3 × 10 mL) and 2 M NaOH (10 mL) sequentially. The organic layer was dried over anhydrous Na2SO4, evaporated in vacuo to afford 2-aminobenzyl-6-substituted-pyridazin-3(2H)-one (11) as a yellow solid, which was used without further purification. To a stirred solution of 11 and triphosgene (1 mmol) in dry dichloromethane (5 mL) was added triethylamine (2 mmol) under nitrogen atmosphere. A solution of the corresponding alcohol (1 mmol) in dichloromethane (5 mL) was added 5-10 min later and the mixture was stirred at room temperature overnight, diluted with dichloromethane (15 mL) and washed with water (3 × 20 mL). The organic phases were separated, combined, dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by using column chromatography to afford the corresponding product.
Statistics shows that 13330-96-6 is playing an increasingly important role. we look forward to future research findings about 4-(Dimethylamino)butan-1-ol.
