반응 단계
A mixture of 100 mg (0.154 mmole) of 2-(5-amino-2-chlorophenyl)-5-n-butyl-4-[[2'-[N-(2-chlorobenzoyl)sulfamoyl]biphenyl-4-yl]methyl]-2,4-dihydro-3H-1,2,4-triazol-3-one (from Example 60), 18.8 mg (0.154 mmole) of 4-(dimethylamino)pyridine (DMAP), 80 μL (82 mg, 0.77 mmole) of butyryl chloride, and 1 mL of pyridine was stirred at room temperature overnight. Work-up of the reaction as in Example 57 provided a 65% yield of the title compound as a white solid, mp >130° C., homogeneous by TLC (9:1 MeOH-CH2Cl2), mass spectrum (FAB) m/e 758 (M+K)+.
