The invention relates to novel compounds of the formula
where X is H, halogen, loweralkyl, loweralkoxy, - CF3, or -OH; R is H, loweralkyl, arylloweralkyl, diarylloweralkyl, loweralkanoyl, arylloweralkanoyl or diarylloweralkanoyl; and R, is H2, 0 or -NR2R3, R2 and R3 being independently H or loweralkyl, or taken together with the nitrogen atom to which they are attached constitute
,R4 in turn being H, loweralkyl, hydroxyloweralkyl, aryl, arylloweralkyl or diarylloweralkyl or pharmaceutically acceptable acid addition salts thereof, which are useful for enchancing memory. The invention relates further to a process and intermediates for the preparation of the above compounds.
本发明涉及式中的新型化合物
其中 X 是 H、卤素、低级烷基、低级烷氧基、-CF3 或 -OH;R 是 H、低级烷基、芳基低级烷基、二芳基低级烷基、低级烷酰基、芳基低级烷酰基或二芳基低级烷酰基;以及 R,是 H2、0 或 -NR2R3,R2 和 R3 独立地是 H 或低级烷基,或与它们连接的氮原子一起构成
R4依次为H、低级烷基、羟基低级烷基、芳基、芳基低级烷基或二芳基低级烷基或其药学上可接受的酸加成盐,可用于增强记忆。本发明还涉及制备上述化合物的工艺和中间体。
