Lithium hydroxide, monohydrate → 1-[(2'-t-Butoxycarbonylbiphenyl-4-yl)methyl]-4-(1-hydroxy-2,2-dimethylpropyl)-2-propylimidazole-5-carboxylic acid

Participants

Reaction Steps

Following a procedure similar to that described in Example 4, 0.78 g of ethyl 1-[(2'-t-butoxycarbonylbiphenyl-4-yl)methyl]-4-(1-hydroxy-2,2-dimethylpropyl)-2-propylimidazole-5-carboxylate [prepared as described in step (d) above] was hydrolyzed, using 209 mg of lithium hydroxide monohydrate, to afford 0.62 g of the title compound as crystals, melting at 207° C.
