Reaction Steps

A mixture of 11.2 g. of 2,6-dimethoxy-4-formyl-benzoic acid methyl ester, 6.3 g. of cyanoacetic acid ethyl ester and three drops of piperidine was heated in an open vessel with stirring to 120°C. and stirred at this temperature for an additional 15 minutes. The residue was recrystallized from ethyl acetate and yielded α-cyano-3,5-dimethoxy-4-methoxycarbonyl-cinnamic acid ethyl ester, having a m.p. of 142°-144°C.
