摘要:
Aminoalkylbenzene derivative of the formula: wherein
A is oxygen or sulfur; Y is oxo, thioxo, or cyanoimino; a is an integer of 1 to 3; b is an integer of 0 to 3; c is an integer of 1 to 4; R 1 is alkyl; R 2 is hydrogen or alkyl; or R 1 and R 2 taken together represent pyrrolidinyl; R is hydrogen, cycloalkyl, trihaloalkyl, alkoxy, dialkylamino, aryl, aroyl, heterocyclic group, or a group of the formula: wherein
R 3 is hydrogen, halogen, amino, alkyl, alkylamino, dialkylamino, alkylthio, or aryloxy; R 4 is hydrogen, alkyl, alkenyl, aryl, or heterocyclic group; or R 3 and R 4 taken together represent alkylidene or aralkylidene;
with the proviso that the above aryl, aroyl, and heterocyclic group can be substituted by 1 to 3 substituents and their acid addition salts being useful as histamine H 2 blockers, especially peptic ulcer remedies.
