PROCEDURE

实验过程

By the procedure of Example 8, Step D, 1-methyl-3-pentyl-1-[2-(trifluoromethyl)phenyl]-3-[[2'(N-trityltetrazol-5-yl)biphenyl-4-yl]methyl]urea (from Step A) was deprotected with aqueous acetic acid. The residual oil was flash chromatographed on silica gel (elution with 3% and then 5% MeOH in CH2Cl2) to give a 31% yield of the title compound as a stiff foam, homogeneous by TLC (95:5 CH2Cl2 -MeOH); FAB-MS m/e 523 (M+1).
