Reaction Steps
Add oxalyl chloride (0.050 mL, 0.57 mmol) to a suspension of 4-cyano-5-ethyl-3-(4-thiazol-2-yl-phenyl)-thiophene-2-carboxylic acid (0.15 g, 0.44 mmol) and DMF (0.1 mL) in dichloromethane at 0° C. Stir 1 h at 23° C. and add 1M solution of ammonia in dioxane (5 mL). Concentrate in vacuo, suspend the solid in ethyl acetate and filter to give 0.052 g of the title compound as a white solid. Mass spectrum ESI positive (m/z): 340 (M+1), 362 (M+23).
