This invention concerns the compounds of formula (I) the N-oxide forms, the pharmaceutically acceptable acid addition salts and the stereochemically isomeric forms thereof, wherein R1 is C1-6alkyloxy, C2-6alkenyloxy or C26alkynyloxy; R2 is hydrogen or C1-6alkyloxy, or when taken together R1 and R2 may form a bivalent radical of formula wherein in said bivalent radicals one or two hydrogen atoms may be substituted with C1-6alkyl, R3 is hydrogen or halo; L is C3-6cycloalkyl, C5-6cycloalkanone, C2-6alkenyl optionally substituted with aryl, or L is a radical of formula -Alk-R4, -Alk-NR5R6, 1-R6-4-piperidinyl, Alk-X-R7, -Alk-Y-C(=O)-R9 or -Alk-Y-C(=O)-NR11R12, wherein each Alk is C1-12alkanediyl; R4 is hydrogen, C1-6alkylsulfonylamino, C36cycloalkyl, C5-6cycloalkanone, Ar-, di(Ar)methyl, Ar-oxy- or Het1; R5 is hydrogen or C1-6alkyl; R6 is Het2; R7 is hydrogen, C1-6alkyl, hydroxyC16alkyl, C3-6cycloalkyl or Ar or Het2; X is O, S, SO2 or NR8; said R8 being hydrogen, C1-6alkyl or Ar; R9 is hydrogen, C1-6alkyl, C3-6cycloalkyl, Ar, ArC16alkyl, di(Ar)methyl, C1-6alkyloxy or hydroxy; Y is NR10 or a direct bond; said R10 being hydrogen, C1-6alkyl or Ar; R11 and R12 each independently are hydrogen, C1-6alkyl, C3-6cycloalkyl, Ar or ArC1-6alkyl, or R11 and R12 combined with the nitrogen atom bearing R11 and R12 may form a pyrrolidinyl or piperidinyl ring both being optionally substituted with C1-6alkyl, amino or mono or di(C1-6alkyl)amino, or said R11 and R12 combined with the nitrogen bearing R11 and R12 may form a piperazinyl or 4-morpholinyl radical both being optionally substituted with C1-6alkyl. Processes for preparing said products, formulations comprising said products and their use as a medicine are disclosed, in particular for treating conditions which are related to impairment of gastric emptying.
