Hydrochloric Acid → Methyl (S)-N-{2-butyl-1-[(2'-carboxybiphenyl-4-yl)methyl]-4-hydroxymethylimidazole-5-carbonyl}prolinate

Participants

Reaction Steps

Following a procedure similar to that described in Example 53, but using 529 mg of succinimido 1-[(2'-t-butoxycarbonylbiphenyl-4-yl)methyl]-2-butyl-4-hydroxymethylimidazole-5-carboxylate [prepared as described in Example 52(a)], 180 mg of methyl (S)-prolinate hydrochloride and 0.2 ml of triethylamine, 0.39 g of the hydrochloride of the title compound was obtained as an amorphous powder, melting at above 120° C.
