Chloroform → Methyl 4-[({2-[(tert-butoxycarbonyl)amino]-5-thien-2-ylphenyl}amino)carbonyl]benzoate

Participants

Reaction Steps

Methyl 4-(chlorocarbonyl)benzoate (1.40 g, 7.07 mmol) and tert-butyl [2-amino-4-(2-thienyl)phenyl]carbamate (2.05 g, 7.07 mmol) were combined in pyridine (10 mL) and stirred at room temperature for 18 h. The reaction mixture was poured into 3:1 CHCl3:MeOH, washed with 2 N HCl and 2 N NaOH, dried (Na2SO4), and evaporated to give the desired product as a colorless solid. MS: cal'd 475 (MNa+), exp 475 (MNa+).
