PROCESS FOR PREPARING HETEROCYCLIC COMPOUNDS

Heterocyclic cpds. of formula (I) and their salts are prepd. by reacting a cpd. of formula (II) with a cpd. of formula (III). In the formula, R1= C1-6 acyl; A= C1-6 alkylene; Y= O, S, carbonylimino or iminocarbonyl; Het indicates 5- or 6- membered heterocyclic ring contg. 1-3 O, S or N; R3, R4, R5=...

Summary:Heterocyclic cpds. of formula (I) and their salts are prepd. by reacting a cpd. of formula (II) with a cpd. of formula (III). In the formula, R1= C1-6 acyl; A= C1-6 alkylene; Y= O, S, carbonylimino or iminocarbonyl; Het indicates 5- or 6- membered heterocyclic ring contg. 1-3 O, S or N; R3, R4, R5= absent or C1-6 alkyl, OH, SH, C1-6 alkoxy, C1-6 alkylthio, oxo, thioxo or carboxy. (I) strongly antagonise the actions of SRS-A and are useful for the prophylaxis and treatment of various allergic diseases.
