With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5381-20-4,Thianaphthene-3-carboxaldehyde,as a common compound, the synthetic route is as follows.
General procedure: An aqueous solution of NaOH (3M, 1.6mL) was added to a solution of aromatic ketone (1mmol) and 3-methoxybenzaldehyde (1.2 eq), in EtOH (1-2mL). The reaction was stirred at r.t for 18-24h. The reaction mixture was cooled in an ice-water bath and acidified to pH 2 with concentrated HCl (37%). The solid formed was filtered, washed with ethanol and then further purified by recrystallization from ethanol. When no precipitate occurred, the reaction mixture was extracted with dichloromethane and washed with water and brine. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. Column chromatography was then utilized to purify the desired product., 5381-20-4
5381-20-4 Thianaphthene-3-carboxaldehyde 227328, abenzothiophene compound, is more and more widely used in various fields.
