A suspension of 12.9 g (50 mmol) of methyl 2-phenylmethylthionicotinate and 2.6 g (110 mmol) of sodium hydride in 100 mL of dry N,N-dimethylformamide was stirred for 4 hours at room temperature. The solution was diluted with 200 mL water and acidified with glacial acetic acid. The precipitate was collected, washed with water, and dried to afford 10.6 g (93%) of a white crystalline solid to be used in the next step.
