Hydrochloric Acid → 3-[4-(Methylcarbamoyl)phenyl]prop-2-enoic acid

Participants

Reaction Steps

To a solution of methyl 4-(methylcarbamoyl)cinnamate (75 mg) in methanol (3 ml) was added 1 N aqueous sodium hydroxide solution (0.5 ml) at 40° C. The mixture was stirred at same temperature for 3 hours. 1 N-Hydrochloric acid (0.5 ml) was added to the reaction mixture and evaporated in vacuo. Water was added to the residue, the mixture was filtered and the residue was washed with diethyl ether to give 4-(methylcarbamoyl)cinnamic acid (56 mg) as a colorless powder.
