実験手順

A mixture of 2-mercaptopyridine (1.7 g), potassium t-butoxide (1.7 g) and N,N-dimethylformamide (3 ml) in toluene (15 ml) was stirred at room temperature for 30 minutes. To the mixture was added 4'-nitro-3'-chloroacetophenone (1.5 g) and the resulting mixture was stirred overnight. Water was added and the insoluble material was filtered, washed with toluene and dried to give crystals of 4'-nitro-3'-(2-pyridylthio)acetophenone (1.1 g).
