N-Hydroxysuccinimide → Succinimido 1-[(2'-t-Butoxycarbonylbiphenyl-4-yl)methyl)-4-(1-hydroxy-2,2-dimethylpropyl)-2-propylimidazole-5-carboxylate

Participants

Reaction Steps

Following a procedure similar to that described in Example 52(a), but using 300 mg of 1-[(2'-t-butoxycarbonylbiphenyl-4-yl)methyl]-4-(1-hydroxy-2,2-dimethylpropyl)-2-propylimidazole-5-carboxylic acid [prepared as described in step (e) above], 110 mg of N-hydroxysuccinimide and 130 mg of N,N-dicyclohexylcarbodiimide, 321 mg of the title compound were obtained as an amorphous solid.
