Reaktionsschritte
The title compound was prepared from 5-n-butyl-2-(2-chloro-5-nitrophenyl)-2,4-dihydro-4-[(2'-sulfamoylbiphenyl-4-yl)methyl]-3H-1,2,4-triazol-3-one (from Example 59, Step C) and 2-phenoxybenzoic acid (2.5 equivalents), CDI (2.5 equiv), and DBU (2.5 equiv) according to the procedure of Example 51. Flash chromatography of the crude product on silica gel (gradient elution with 0.5-1% MeOH in CH2Cl2) gave a 55% yield of the desired material as a stiff foam, homogeneous by TLC in 95:5 CH2Cl2 --MeOH; mass spectrum (FAB) m/e 738 (M+1)+.
