This invention is directed to compounds having the formula: ##STR1## wherein: A represents an aromatic or heterocyclic ring having two of its carbon atoms held mutually with the oxazepine, thiazepine or diazepine moiety selected from the group consisting of benzene, naphthalene, a quinoline, a pyridine in any of its four positions, any of which rings are optionally substituted by one or two Y radicals selected from the group consisting of halo, loweralkyl, loweralkoxy, diloweralkylamino, nitro, amino, lower acylamino, trilfuoromethyl, phenyl or phenyl substituted by one to three Y' groups selected from halo, loweralkyl, loweralkoxy, diloweralkylamino, nitro, amino, loweracylamino or trifluoromethyl, E is selected from oxygen, sulfur or ##STR2## B is selected from the group consisting of loweralkyl, cycloalkyl or phenyl-loweralkyl wherein phenyl is optionally substituted by one or two radicals selected from halo, loweralkyl, loweralkoxy, nitro or trifuoromethyl, N is 1 or 2, R.sup.4 and R.sup.5 are selected from hydrogen or loweralkyl (1-5 C), X is halogen selected from chlorine, bromine, cyano or 1-phthalimido, the optical isomers thereof and the acid addition salts thereof. These compounds are valuable intermediates in the preparation of compounds having antihistaminic utility.
本发明涉及具有以下通式结构的化合物:##STR1## 其中:A代表具有两个碳原子与噁嗪、噻嗪或二嗪部分相互连接的芳香或杂环环,该环选自苯、萘、喹啉、吡啶的任一四个位置中的任何一个,这些环任选地被一个或两个Y基团取代,Y基团选自卤素、低级烷基、低级烷氧基、二低级烷基氨基、硝基、氨基、低级酰基氨基、三氟甲基、苯基或被一个至三个Y'基团取代的苯基,Y'基团选自卤素、低级烷基、低级烷氧基、二低级烷基氨基、硝基、氨基、低级酰基氨基或三氟甲基,E选自氧、硫或##STR2## B选自低级烷基、环烷基或苯基-低级烷基,其中苯基任选地被一个或两个选自卤素、低级烷基、低级烷氧基、硝基或三氟甲基的基团取代,N为1或2,R.sup.4和R.sup.5选自氢或低级烷基(1-5C),X为选自氯、溴、氰基或1-邻苯二甲酰亚胺的卤素,其光学异构体及其酸加成盐。这些化合物是有价值的中间体,用于制备具有抗组胺活性的化合物。
