Participants

Reaction Steps

A solution of 0.36 g of methyl 1-[(2'-t-butoxycarbonylbiphenyl-4-yl)methyl]-2-butyl-4-hydroxymethylimidazole-5-carboxylate (prepared as described in Example 1) in 4 ml of a 4N solution of hydrogen chloride in dioxane was allowed to stand at room temperature for 4 hours. At the end of this time, the reaction mixture was concentrated by evaporation under reduced pressure, and the residue was triturated with ethyl acetate, to give crystals, which were collected by filtration to give 0.35 g of the title compound in the form of its hydrochloride, melting at 192°-195° C. (with decomposition).
