Abstract

NEW MATERIAL:A 3,4-dihydrocarbostyril devivative of formula I: [R1 is lower alkanoyl or 2,3-epoxypropyl group; R2 is H, 2-tetrahydropyranyl group, R3 CO(CH2)m-(R3 is lower alkyl group; m is an integer 1W4), or formula II; R2 is not H or R3 CO(CH2)m-when R1 is 2,3-epoxypropyl group].
EXAMPLE: 5-Acetyloxy-8-hydroxy-3,4-dihydrocarbostyril.
USE: An intermediate for remedies of angina pectoris, arrhythmia, and hypertension.
PROCESS: The acyl group (the 8-position) of a 5,8-diacyloxy-3,4-dihydrocarbostyril of formula III is selectively hydrolyzed to give the compound of formula I: (R1 is lower alkanoyl group; R2 is H).
