Participants

Reaction Steps

A solution of 2.0 g methyl-1-(2-(1-adamantyl)ethyl)-5-diphenylacetyl-4,5,6,7-tetrahydro-1H-imidazo-[4,5-c]-pyridine-6-carboxylate in tetrahydrofuranmethanol (3:1, 20 mL) is treated at 25° C. with 4.1 mL 1N NaOH. After 6 hr the solution is evaporated, the residue is suspended in 10 mL water and treated with 4.1 mL 1N HCl. The resulting precipitate is collected by filtration and dried to afford a white solid, 1-(2-(1-adamantyl)ethyl)-5-diphenylacetyl-4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridine-6-carboxylic acid. MS (FAB) 524 (M+1). mp 168°-175° C. or 187° to 200° C. dec.
