Reaktionsschritte
The reaction of 5-n-butyl-2,4-dihydro-4-[(2'-sulfamoylbiphenyl-4-yl)methyl]-2-[2-(trifluoromethyl)phenyl]-3H-1,2,4-triazol-3-one (from Step C) with benzoyl chloride was carried out according to the method of Example 13, Step C. Flash chromatography of the crude product on silica gel (gradient elution with 0.5-5% MeOH in CH2Cl2) provided a 75% yield of the title compound as white crystals, mp 91°-93° C.; satisfactory purity by TLC 19:1 CH2Cl2 --MeOH; mass spectrum (FAB) m/e 673 (M+K)+.
