Ethyl 1-[(2'-t-butoxycarbonylbiphenyl-4-yl)methyl]-4-formyl-2-propylimidazole-5-carboxylate → Ethyl 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 59(b), 1.14 g of ethyl 1-[(2'-t-butoxycarbonylbiphenyl-4-yl)methyl]-4-formyl-2-propylimidazole-5-carboxylate [prepared as described in step (c) above] was reacted with 2.4 ml of a 2M solution of t-butylmagnesium bromide in tetrahydrofuran, to afford 0.78 g of the title compound as a viscous oil.
