Abstract

NEW MATERIAL:A compound of formula I (R is H, alkyl, aralkyl, pyridylmethyl; R1 is H, halogen; R2 is H, alkyl; R3 is alkyl, alkoxy; A is alkylene) or its salt.
EXAMPLE: 2-p-Chlorophenyl-5-(2,5-dimethylphenoxy)-4-oxazoleacetic acid methyl ester.
USE: Low toxic blood lipid depressing agent, and its synthetic intermediate.
PROCESS: The objective compound III is prepared by the dehydrative ring-closure of a compound II (R4 is R excepting H) in the presence of a dehydrating agent such as phosphorus pentoxide at an elevated or room temperature. The compound I wherein R is H, is prepared by the hydrolysis of the compound III.
