Triethylamine → Methyl 3-[(4-cyanobenzoyl)amino]thiophene-2-carboxylate

Participants

Reaction Steps

A mixture of 4-cyanobenzoyl chloride (1.0500 g, 6.4 mmol), methyl 3-aminothiophenecarboxylate (1.0000 g, 6.4 mmol), and triethylamine (1 mL, 7.0 mmol) in dichloromethane was stirred at room temperature for 18 hours. The mixture was poured into a separatory funnel and washed by 1 N HCl. The organic layers were combined, dried over MgSO4, concentrated in vacuo, and chromatographed through a silica gel column to give the title compound 1.6588 g (91%). ES-MS 287 (M+1).
