Reaction Steps

A solution of 4-methoxy-3-nitroanilinesulfonylacetic acid (10 mmol) and 2,4,6-trimethoxy-benzaldehyde (10 mmol) in glacial acetic acid (15 mL) was stirred at room temperature for 10 min. A catalytic amount of benzylamine (300 microliters) was added to the solution. The solution was then refluxed for 8 h. The reaction mixture was then cooled to room temperature. To the cooled reaction mixture was added ethyl acetate. A solid precipitate formed and was separated by filtration. Additional of ethyl acetate (30 mL) was added and the resulting mixture was washed sequentially with saturated sodium bicarbonate, dilute HCL and brine. The organic layer was dried over anhydrous sodium sulfate and then concentrated under vacuum. The solid residue obtained was recrystallized from 2-propanol. (m.p 177–179° C.; yield 48–52%).
