Abstract

PURPOSE: To obtain a condensed heterocyclic compound containing nitrogen and an anti-inflammatory agent, analgesic, antiallergic agent and central nervous suppressant, in high yield economically, by hydrolyzing a novel quaternary salt of condensed heterocyclic compound containing nitrogen.
CONSTITUTION: A compound of formula I [R1 is H, halogen or halogen-substituted alkyl; R2 is alkylene; R3 is alkyl or hydroxyalkyl; X1 is O or S; X2 is halogen or alkylthio; Y- is halogen ion, or ion of group -OSO2R4 or -OSO2OR5 (R4 is alkyl, phenyl, etc.; R5 is alkyl)] is hydrolyzed to give a compound of formula II. The compound of formula I is a novel substance and has a pharmacological action useful for the circulatory system and nervous system, and is favorable for an antimicrobial agent.
