Participants

Reaction Steps

To a mixture of 43.9 g of methyl 4-[2-(4-aminophenyl)ethyl]benzoate, 22.3 g of cyanoacetic acid, and 150 mL of DMF was added 49.5 g of WSC.hydrochloride under ice cooling. After the reaction mixture was stirred for 24 hours at room temperature, 450 mL of water was added thereto at room temperature, followed by stirring for 30 minutes at room temperature. Thereafter, the precipitate was collected by filtration, thereby obtaining 54.2 g of methyl 4-(2-{4-[(cyanoacetyl)amino]phenyl}ethyl)benzoate.
