  This invention provides compounds of the formula (I) and (II): 1 or the pharmaceutically acceptable esters thereof, and the pharmaceutically acceptable salts thereof: wherein R 1 is hydrogen or halo; R 2 and R 3 are independently hydrogen or C 1-6 alkyl; R 4 and R 5 are independently hydrogen or C 1-6 alkyl; R 6 is hydrogen, C 1-12 alkyl, C 1-6 alkoxy (C 1-6 )alkyl or C 1-12 alkyl substituted by up to 3 substituents selected from the groups consisting of C 3-8 cycloalkyl, aryl, heteroaryl and heterocyclic; R 7 and R 8 are hydrogen or taken together may form alkylene chain having one or two carbon atoms; R 9 is C 1-6 alkyl or C 3-8 cycloalkyl; R 10 is C 1-6 alkyl or NR 11 R 12 ; L is (CR 11 R 12 ) n or NR 11 ; M is NR 11 or (CR 11 R 12 ) n ; R 11 and R 12 are independently hydrogen or C 1-6 alkyl; n is an integer from 0 to 5; and m is an integer from 0 to 2; said heterocyclic, aryl and heteroaryl are unsubstituted or are substituted by at least one substituent selected from the group consisting of halo and C 1-6 alkyl; with the proviso that when R 9 is C 1-6 alkyl, L is not NR 11 . These compounds have 5-HT 4 receptor binding activity, and thus are useful for the treatment of gastroesophageal reflux disease, non-ulcer dyspepsia, irritable bowel syndrome or the like in mammalian, especially humans. This invention also provides a pharmaceutical composition comprising the above compound.

  本发明提供了式(I)和(II)的化合物：1或其药学上可接受的酯和药学上可接受的盐：其中，R1是氢或卤素；R2和R3分别是氢或C1-6烷基；R4和R5分别是氢或C1-6烷基；R6是氢、C1-12烷基、C1-6烷氧基(C1-6)烷基或C1-12烷基，其被选自C3-8环烷基、芳基、杂芳基和杂环的最多3个取代基取代；R7和R8是氢或一起形成具有一个或两个碳原子的烷基链；R9是C1-6烷基或C3-8环烷基；R10是C1-6烷基或NR11R12；L是(CR11R12)或NR11；M是NR11或(CR11R12)n；R11和R12分别是氢或C1-6烷基；n是0到5的整数；m是0到2的整数；所述的杂环、芳基和杂芳基未取代或被至少一个取代基所取代，所述取代基被选自卤素和C1-6烷基；但当R9是C1-6烷基时，L不是NR11。这些化合物具有5-HT4受体结合活性，因此在哺乳动物，尤其是人类的治疗胃食管反流病、非溃疡性消化不良、肠易激综合征等方面是有用的。本发明还提供了包含上述化合物的制药组合物。
