A process for preparing a compound of the formula (IV) or a salt thereof,
, wherein R¹ is an optionally substituted aliphatic or aromatic hydrocarbon residue or an optionally substituted aromatic heterocyclic group, one of Y and Z is a nitrogen atom and the other is a methine group which may be optionally substituted with a lower alkyl group, Ar is a halogenated phenyl group, and (R) shows that the carbon atom marked with (R) has (R)-configuration, in a short period, by simple processes and with high yield and purity; and an azole compound of the formula (IV'),
, wherein Ar' is a monofluorophenyl group, and the other symbols have the same meanings as above, or a salt thereof, which are useful for an antifungal therapeutic agent.
一种制备式(IV)化合物或其盐的方法,其中R¹是可选取的取代脂肪族或芳香烃基残基或可选取的取代芳香杂环基团,Y和Z中的一个是氮原子,另一个是可能被低烷基取代的甲基基团,Ar是卤代苯基团,(R)表示标有(R)的碳原子具有(R)-构型,通过简单的过程,在短时间内高产量和高纯度地制备出所述化合物;以及式(IV')的唑类化合物或其盐,其中Ar'是单氟苯基团,其他符号具有与上述相同的含义,这些化合物对于抗真菌治疗剂是有用的。
