The invention concerns a compound formula II ##STR1## or an acid addition salt thereof, wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, and R.sup.7 are the same or different and represent hydrogen, or loweralkyl, cycloalkyl or lower aralkyl, any of which radicals may be substituted by lower alkyl, lower alkoxy or CF.sub.3 or phenyl radicals which may be substituted by lower alkyl or CF.sub.3 or R.sup.2 and R.sup.3 taken together, form a 5, 6 or 7 membered saturated ring R.sup.4 and R.sup.5 may also represent lower alkoxy, or cycloalkoxy, n is 1, 2, or 3 and, if more than one R.sup.4 radical is present the R.sup.4 radicals may be the same or different with the provisos that (1) when R.sup.1, R.sup.2, R.sup.3, R.sup.4, and R.sup.5 are all hydrogen, R.sup.6 R.sup.7 are not both hydrogen, (2) when R.sup.1 and R.sup.3 are both phenyl and when R.sup.1 is methyl and R.sup.4 is methyl then R.sup.6 and R.sup.7 are not both methyl, and (3) when R.sup.1 is hydrogen or methyl, R.sup.3 is hydrogen or methyl and R.sup.2, R.sup.4, R.sup.5, and R.sup.6 are all hydrogen then R.sup.7 is other than unsubstituted phenyl. The compounds are intermediates for other compounds with anti-ulcer activity.
该发明涉及化合物公式II ##STR1## 或其酸盐,其中R.sup.1、R.sup.2、R.sup.3、R.sup.4、R.sup.5、R.sup.6和R.sup.7相同或不同,代表氢,或较低烷基,环烷基或较低芳基,其中任何一个基团可以被较低烷基,较低烷氧基或CF.sub.3或苯基所取代,该苯基可以被较低烷基或CF.sub.3所取代,R.sup.2和R.sup.3一起形成5、6或7个成员的饱和环,R.sup.4和R.sup.5也可以代表较低烷氧基或环烷氧基,n为1、2或3,并且,如果存在多个R.sup.4基团,则R.sup.4基团可以相同或不同,但有以下限制:(1)当R.sup.1、R.sup.2、R.sup.3、R.sup.4和R.sup.5都是氢时,R.sup.6、R.sup.7不都是氢,(2)当R.sup.1和R.sup.3都是苯基,且当R.sup.1为甲基且R.sup.4为甲基时,则R.sup.6和R.sup.7不都是甲基,(3)当R.sup.1为氢或甲基,R.sup.3为氢或甲基且R.sup.2、R.sup.4、R.sup.5和R.sup.6都是氢时,则R.sup.7不是未取代的苯基。这些化合物是具有抗溃疡活性的其他化合物的中间体。
