Pyridine → 2,2,2-Trichloroethyl [4-(propionylamino)phenyl]carbamate

Participants

Reaction Steps

To a solution of N-(4-aminophenyl)propanamide (2.00 g, 10.3 mmol) and pyridine (2.50 ml, 30.9 mmol) in N,N-dimethylacetamide (40 ml) was added 2,2,2-trichloroethyl chloroformate (2.13 ml, 15.5 mmol) under ice-cooling, and the mixture was stirred under ice-cooling for 2 hours. The reaction mixture was poured into ice-water, and 3.41 g (97.4%) of the desired product was collected by filtration as a solid.
