Participants

Reaction Steps

To a mixture of 7.00 g (33.15 mmol) of 6-nitroveratraldehyde (80%) and 3.4 mL (38.42 mmol) of methyl cyanoacetate in 70 mL of methanol is added 0.7 mL of piperidine. An additional 100 mL of methanol is added and the thick suspension is warmed slightly until the mixture stirred freely. After stirring at room temperature for 1 hour, the solids are collected by filtration washing with methanol followed by diethyl ether to give 7.57 g (78%) of methyl 2-cyano-3-(4,5-dimethoxy-2-nitrophenyl)-2-propenoate as a pale yellow solid, mp 162-164° C.
