(2-Fluoro-3-trifluoromethyl-phenyl)-(4-methoxy-phenyl)-methanone (59.6 mg, 0.2 mmol) was dissolved in 1 ml of pyridine. Hydrazine hydrate (97 μl, 2 mmol) and 4-(dimethylamino)-pyridine (24.4 mg, 0.2 mmol) were added. The reaction mixture was stirred overnight at 100° C. After cooling to room temperature, EtOAc and 1M HCl were added. The organic phase was washed three times with brine, dried over MgSO4 and concentrated under vacuum. Purification of the crude product by flash column chromatography on silica gel (n-heptane/ethyl acetate, 85:15) afforded 56 mg of the analytically pure product.
