Procedure

Acetyl chloride (388 μl, 5.44 mmol) was added dropwise to a solution of N-(4-(2-nitro-2-methylpropoxy)-3-(4-chloro-2-methyl-2H-pyrazol-3-yl)phenyl)-3-(trifluoromethyl)benzamide (270 mg, 0.544 mmol) in methanol (5.0 mL). Zinc dust (356 mg, 5.44 mmol) was added, and the mixture was stirred at 23° C. After 1 hour, the mixture was filtered and the filtrate was evaporated to dryness. The residue was taken up in ammonium hydroxide (35%), diluted with water and extracted with ethyl acetate. The organic layer was washed with brine, dried with sodium sulfate, filtered, and evaporated to dryness to afford the title compound as a colorless foam which was used without further purification. LCMS m/z (%) 469.4 (M+H, 37Cl 46.9), 467.2 (M+H, 35Cl 86.1), 452.2 (51.6%), 450.1 (100.0%).
