Reaction Steps
An aq. 6 M NaOH solution (1.05 eq) was added to a methonolic solution of 4-ethylbenzaldehyde (1 eq) and nitromethane (1 eq) stirred at 0° C. During the slow addition of base, maintain the temperature between 10-15° C. The reaction generates a thick white precipitate. To allow smooth stirring, an additional amount of MeOH was added. After stirring for an additional 15 min., the ice bath was removed. Upon reaching RT, water was added to the reaction, which subsequently turned clear. The clear solution was added to a flask containing a stirred 6M aq. HCl solution. A yellow crystalline precipitate formed. After 10 min., the crystalline product was filtered, washed thoroughly with water, suction dried and recrystallized from abs. EtOH. 4-ethyl trans-beta-nitrostyrene (2) was afforded as a yellow crystalline product in 52% yield and >99% purity (LC/MS m/z 178.2 MH.
