EPOXY COMPOUND AND PRODUCTION METHOD THEREOF Russian patent published in 2012 - IPC C07D405/12 C07D498/04 C07D303/18

Abstract RU 2459822 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a novel intermediate epoxy compound of general formula (2), where R¹ represents hydrogen or a lower alkyl group; and R² represents a piperidinyl group of general formula (A1), where R³ represents a phenoxy group, having a halogen-substituted lower alkoxy group, substituted with a phenyl group, and other similar groups; and n is an integer from 1 to 6, to obtain 2,3-dihydroimidazo[2,1-b]oxazole. The invention also relates to specific epoxy compounds, a method of producing epoxy compounds of formula (2) and a method of producing 2,3-dihydroimidazo[2,1-b]-oxazole using a novel intermediate epoxy compound.

EFFECT: obtaining 2,3-dihydroimidazo[2,1-b]oxazole with high output and high purity.
