PROCEDURE

实验过程

By the procedure of Example 13, Step C, 5-n-butyl-2-(2-chlorophenyl)-2,4-dihydro-4-[(2'-sulfamoylbiphenyl-4-yl)methyl]-3H-1,2,4-triazol-3-one (from Example 13, Step B) was reacted with 4-fluorobenzoyl chloride. Column chromatography on silica gel (gradient elution with 0.5-5% MeOH in CH2Cl2) afforded an 80% yield of the title compound as cream-colored crystals, mp 118°-120° C., satisfactory purity by TLC in 9:1 CH2Cl2 --MeOH; mass spectrum (FAB) m/e 619 (M+1)+
