The present invention provides novel intermediates for the preparation of 2,3-dihydroimidazo [2,1-b] oxazole compounds in high yield and high purity, and methods for preparing these intermediates. The present invention provides an epoxy compound represented by the general formula (2), a method for producing the epoxy compound, and a method for producing an oxazole compound using the epoxy compound:n n n n n n n n [Wherein, R 1 represents hydrogen or a lower alkyl group;n n n R 2 represents a piperidyl group represented by the formula (A1) and the like:n n n n n n n n (Wherein R 3 represents a phenoxy group in which a halogen-substituted lower alkoxy group is substituted on a phenyl group),n n n n represents an integer of 1 to 6; |
