This invention provides compounds of the structure ##STR1## where R.sub.1 is C.sub.3 -C.sub.20 alkyl or arylalkyl; R.sub.2 is hydrogen, loweralkanoyl, loweralkylsulfonyl, loweralkoxycarbonyl, carbamoyl or ##STR2## wherein X is an alkylene group having from 2 to 4 carbon atoms; and R.sub.3 and R.sub.4 are the same or different members of the group consisting of hydrogen or loweralkyl, or R.sub.3 and R.sub.4 taken together form a 5-, 6-, or 7-member heterocyclic ring; and the pharmaceutically acceptable acid addition salts thereof. The compounds of this invention are useful as analgesics, tranquilizers and sedative-hypnotics.
这项发明提供了结构为##STR1##的化合物,其中R.sub.1为C.sub.3 -C.sub.20烷基或芳基烷基;R.sub.2为氢、较低烷酰基、较低烷基磺酰基、较低烷氧羰基、氨基甲酰基或##STR2##,其中X为具有2至4个碳原子的烷基基团;而R.sub.3和R.sub.4为氢或较低烷基中的相同或不同成员,或者R.sub.3和R.sub.4一起形成一个5、6或7元杂环环;以及其药用可接受酸盐。这些化合物可用作镇痛药、镇静剂和催眠药。
