Procedure
Sodium hydride (60%; 40 mg) was added to an ice-cooled solution of ethyl 5-[4-(formylamino)phenyl]-4-[4-(methylsulfonyl)phenyl]thiophene-2-carboxylate (0.35 g) in N,N-dimethylformamide (10 ml). The mixture was stirred at ambient temperature for 30 minutes, and to the resulting mixture was added methyl iodide (0.23 g) at 5° C. The mixture was stirred at ambient temperature for 1.5 hours and poured into ice-water. The precipitates were collected, washed with water, and dried in vacuo to give ethyl 5-[4-(N-formylmethylamino)phenyl]-4-[4-(methylsulfonyl)phenyl]thiophene-2-carboxylate (0.34 g).
