Participants

Reaction Steps

To a mixture of 3.00 g (11.58 mmol) of 4-(2-chloroethoxy)-5-methoxy-2-nitrobenzaldehyde and 1.5 mL (16.95 mmol) of methyl cyanoacetate in 30 mL of methanol is added 0.3 mL of piperidine. The mixture is heated at reflux for 5 minutes then cooled slightly and the thick suspension is collected by filtration washing with ethyl acetate followed by diethyl ether to give 1.07 g (27%) of methyl (2E)-2-cyano-3-[4-(2-chloroethoxy)-5-methoxy-2-nitrophenyl]-2-propenoate as a yellow solid, mp softens at 121° C., melts at 157-160° C.
