실험 절차

At room temperature, under N2, a solution of 34 mg (0.052 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), 6.4 mg (0.052 mmole) of DMAP, 23 mg (0.26 mmole) of propyl isocyanate, and 1 mL of pyridine was stirred overnight. After quenching with water, the organic material was extracted with EtOAc, washed with water and brine, and dried over sodium sulfate. The crude product obtained after filtration and removal of volatiles was flash chromatographed over silica gel (gradient elution with 0.5-5% MeOH/CH2Cl2) to give 23 mg (61%) of the desired compound as a white solid, mp >208° C. (gradual), homogeneous by TLC (9:1 MeOH/CH2Cl2), mass spectrum (FAB) m/e 773 (M+K)+.
