Reaction Steps

A mixture of 388 mg (0.625 mmol) of 4-[[2'-(N-t -butylsulfamoyl)-3-fluorobiphenyl-4-yl]methyl]-2,4-dihydro-5-ethyl-2-[5-nitro-2-(trifluoromethyl)phenyl]-3H-1,2,4-triazol-3-one (from Step A), 6 mL of EtOH, 8 mL of EtOAc, and 30 mg of 5% PtO2 was shaken with hydrogen for 3.5 hours on a Parr hydrogenation apparatus. Removal of the catalyst followed by evaporation of volatiles gave 383 mg (quantitative) of a cream-colored solid [top >105° C. (gradual)] of sufficient purity to be used in the next step without further purification; mass spectrum (FAB) m/e 599 (M+Li)+.
