Reaction Steps
500 mg (1.90 mmol) of 4-(2-chloroethoxy) acetoacetic acid benzyl ester, 260 mg (1.90 mmol) of 3-chlorobenzaldehyde, acetic acid and piperidine were heated and stirred at room temperature for 24 hours in 3 ml of 2-propanol. 280 mg (1.90 mmol) of 3-aminocrotonate 2-cyanoethyl ester was added and further heated and stirred at 50° C. for 48 hours. 2-propanol was evaporated under reduced pressure. The residue was purified by the silica gel chromatography (hexane/ethyl acetate=1/1) to obtain the title compound.
