Participants

Reaction Steps

Following a procedure similar to that described in Example 53, but using 0.32 g of succinimido 1-[(2'-t-butoxycarbonylbiphenyl-4-yl)methyl]-2-butyl-4-hydroxymethylimidazole-5-carboxylate [prepared as described in Example 52(a)], 0.11 g of t-butyl glycinate hydrochloride and 80 mg of 4-dimethylaminopyridine, 0.21 g of the hydrochloride of the title compound was obtained as an amorphous powder melting at above 110° C.
