PROBLEM TO BE SOLVED: To provide a method for producing a specific heterocyclic compound exhibiting ACAT-inhibiting activities and lipid peroxidation-inhibiting activities, and satisfying as an industrial production method in the yield and in the aspect of operation, and further to provide an intermediate therefor. SOLUTION: This method for producing the heterocyclic compound comprises producing the compound 4 from the compound 1 through the compounds 2 and 3 [wherein, R2, R3 and R5 are each independently hydrogen, a lower alkyl group or a lower alkoxy group; R4 is an alkyl group, an alkoxyalkyl group, an alkylthioalkyl group, a cycloalkyl group, a cycloalkylalkyl group, an aryl group, an arylalkyl group or -NHR (R6 is an alkyl group, a cycloalkyl group, a cycloalkylalkyl group, an aryl group or an arylalkyl group); A is an alkylene group; and Z is -CH2CH2- or -CH=CH-].
