This invention relates to novel compounds of the formula ##STR1## wherein R.sub.1 is hydrogen or alkyl having from 1 to 4 carbon atoms; R.sub.2 is halogen, hydrogen, or alkyl having from 1 to 4 carbon atoms; and R is (1-methyl-4-piperidinyl)methyl, (1-methyl-1,2,5,6-tetrahydro-4-pyridinyl)methyl, 1-methyl-1,2,5,6-tetrahydro-4-pyridinyl, (1-methyl-4-piperidinylidene)-methyl, or (8-methyl-8-azabicyclo\x9b3.2.1!oct-3-yl)-methyl, each of which can \n' optionally have an additional methyl substituent on the heterocyclic ring, and non-toxic, pharmacologically acceptable acid addition salts thereof. The compounds as well as their salts are useful as anti-ulcerogenics.
这项发明涉及以下结构的新化合物:其中R.sub.1为氢或含有1至4个碳原子的烷基;R.sub.2为卤素、氢或含有1至4个碳原子的烷基;R为(1-甲基-4-哌啶基)甲基、(1-甲基-1,2,5,6-四氢-4-吡啶基)甲基、1-甲基-1,2,5,6-四氢-4-吡啶基、(1-甲基-4-哌啶基亚)-甲基或(8-甲基-8-氮杂双环[3.2.1]辛-3-基)-甲基,其中每个基在杂环环上可以选择性地有一个额外的甲基取代基,并且其无毒、药理学上可接受的酸盐。这些化合物及其盐可用作抗溃疡剂。
