実験手順

By the procedure of Example 13, Step C, 5-n-butyl-2,4-dihydro-4-[(2'-sulfamoylbiphenyl-4-yl)methyl]-2-[2-(trifluoromethyl)phenyl]-3H-1,2,4-triazol-3-one (from Example 16, Step C) was reacted with diphenylacetyl chloride. The crude product was evaporated twice from toluene and flash chromatographed twice on silica gel (gradient elution with 0.1-1% MeOH in CH2Cl2 and then approx. 0.01-1% MeOH in CH2Cl2) to give a 73% yield of the title compound as off-white crystals, mp 144°-146° C.; homogeneous by TLC in 19:1 CH2Cl2 --MeOH; mass spectrum (FAB) m/e 725 (M+1)+.
