실험 절차

Using the method of Example 76, Step F, 4-(4-bromo-2-fluorobenzyl)-5-n-butyl-2-(2-chloro-5-nitrophenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (from Step A) was coupled with 2-(N-t-butylsulfamoyl)-5-n-propylphenylboronic acid (from Example 68, Step B). Flash chromatography of the crude product on silica gel (gradient elution with 6:1 to 2:1 hexane-EtOAc) gave a 43% yield of the title compound as a cream-colored solid, mp 84°-86° C.; homogeneous by TLC (4:1 hexane-EtOAc).
