The present invention provides a method for producing a 1-biphenylmethylimidazole compound having superior angiotensin II receptor antagonistic activity, or an intermediate thereof.
The present invention provides a method for producing a compound having the formula (5) (R1, Ra: H, an alkyl group) by oxidizing a compound having the formula (1) (Ra: H, an alkyl group) using an oxidizing agent in the presence of a radical initiation reagent, and then reacting with an ammonia-generating reagent and a compound having the formula R1CHO(R1: H, an alkyl group) or a compound having the formula R1C(ORb)3 (R1: H, an alkyl group; Rb: an alkyl group).
本发明提供了一种生产具有优良的血管紧张素II受体拮抗活性的1-联苯甲基咪唑化合物或其中间体的方法。本发明提供了一种通过在自由基引发剂存在下使用氧化剂氧化具有式(1)(Ra:H,烷基)的化合物,然后与生成氨试剂和具有式R1CHO(R1:H,烷基)的化合物或具有式R1C(ORb)3(R1:H,烷基;Rb:烷基)的化合物反应,从而生产具有式(5)(R1,Ra:H,烷基)的化合物的方法。
