Participants

Reaction Steps

(2-Amino-5-trifluoromethoxy-phenyl)-phenyl-methanone (0.3 g, 1 mmol), methylsulfonylacetone (0.22 g, 2 mmol) and sodium tetrachloroaurate (III) dihydrate (13 mg, 0.036 mmol) were mixed in 2-propanol (3 mL) and heated at reflux under nitrogen for 5 days. 2-propanol was evaporated and the residue was purified by flash chromatography on silica gel in heptane/ethyl acetate 2:1. One obtained 154 mg (34%) of a white solid. MS: m/z=382 (M+H).
