An object of the present invention is to provide a method for producing an oxazole compound in a high yield. The object can be achieved by a compound represented by Formula (11): wherein R1 is a hydrogen atom or lower-alkyl group; R2 is a 1-piperidyl group substituted at the 4-position with a substituent selected from (A1a) a phenoxy group substituted on the phenyl moiety with one or more halogen-substituted lower-alkoxy groups, (A1b) a phenoxy-substituted lower-alkyl group substituted on the phenyl moiety with one or more halogen-substituted lower-alkyl groups, (A1c) a phenyl-substituted lower-alkoxy lower-alkyl group substituted on the phenyl moiety with halogen, (A1d) a phenyl-substituted lower-alkyl group substituted on the phenyl moiety with one or more halogen-substituted lower-alkoxy groups, (A1e) an amino group substituted with a phenyl group substituted with one or more halogen-substituted lower-alkoxy groups, and a lower-alkyl group, and (A1f) a phenyl-substituted lower-alkoxy group substituted on the phenyl moiety with one or more halogen-substituted lower-alkoxy groups; n is an integer from 1 to 6; and X3 is an organic sulfonyloxy group.
本发明的目的是提供一种高产率生产噁唑化合物的方法。该目的可以通过由式(11)表示的化合物实现:其中R1是氢原子或较低的烷基基团;R2是在4-位被取代的1-哌啶基团,所述取代基选自(A1a)苯氧基在苯基上取代一个或多个卤素取代的较低烷氧基团,(A1b)苯氧基取代的较低烷基基团在苯基上取代一个或多个卤素取代的较低烷基基团,(A1c)苯基取代的较低烷氧基较低烷基基团在苯基上取代卤素,(A1d)苯基取代的较低烷基基团在苯基上取代一个或多个卤素取代的较低烷氧基团,(A1e)氨基取代的苯基取代一个或多个卤素取代的较低烷氧基团和较低烷基基团,以及(A1f)苯基取代的较低烷氧基团在苯基上取代一个或多个卤素取代的较低烷氧基团;n是1到6之间的整数;X3是有机磺酰氧基团。
