Reaction Steps

3-Chloro-thiophene-2-carboxamide (0.145 g, 0.898 mmol) and 4-trifluoromethyl-phenacyl bromide (0.200 g, 0.749 mmol) were placed in a sealed tube and heated at 150° C. for 4 h. The reaction mixture was quenched with ethyl acetate and the residue was purified by column chromatography (gradient 100:1, 20:1 hexane:dichloromethane). The product was further purified by preparative-TLC (100:1, hexane:dichloromethane) to yield 0.0148 g (5.0%) of the title compound as a white solid. 1H NMR (Acetone-d6): 8.58 (s, 1H), 8.01 (d, J=8.1 Hz, 2H), 7.71 (t, 3H), 7.10 (d, J=5.1 Hz, 1H), 7.08 (d, J=5.7 Hz, 1H).
