Procedure

Propyl iodide (0.37 g) was added to a solution of ethyl 2-mercapto-1-[[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl]benzimidazole-7-carboxylate (0.91 g) in ethanol (13 ml) containing 1N NaOH (4.0 ml) and the mixture was stirred at room temperature for 5 hours. The reaction mixture was adjusted to about pH 4 with dilute hydrochloric acid to give crystals. The crystals were collected by filtration and purified by column chromatography on silica gel. Recrystallization from ethyl acetate-hexane gave colorless prisms (0.4 g, 40%), m.p. 177-178° C. (decomp.).
