Triethylamine → HCID 2970608, compound

Participants

Reaction Steps

To a solution of 2-aminothiophene-3-carboxamide (800 mg, 5.63 mmol, 1.0 eq.) in THF (15 mL) and Et3N (626 mg, 6.19 mmol, 1.1 eq.) was added nicotinoyl chloride (795 mg, 5.63 mmol, 1.0 eq.) in anhydrous THF (15 mL) dropwise. The resulted mixture was stirred at room temperature overnight. After the reaction was completed, the volatiles were evaporated. The residue was washed with CH2Cl2 (20 mL). The resulting solid was collected and dried in vacuo to give 1.50 g of N-(3-carbamoylthiophen-2-yl)nicotinamide as a brown solid (quantitative yield). LCMS m/z=248.1 (M+1) (Method B) (retention time=1.34 min).
