PROCESS FOR PRODUCING TETRAZOLYLATED BIPHENYLMETHANE DERIVATIVES

摘要

The present invention relates to a process for producing a tetrazolylated biphenylmethane derivatives (6) or salts thereof in accordance with the below-described reaction scheme wherein R<1> represents an alkyl; R<2> represents H, etc.; Z represents a halogen, etc.; and A represents a cycloalkene, etc. According to the above process, a tetrazolylated biphenylmethane derivative can be industrially and advantageously produced with short steps.
