Patent number: 6498158
Abstract: The present invention is concerned with the compounds of formula
the N-oxides, the pharmaceutically acceptable addition salts and the stereochemically isomeric forms thereof, wherein p is 0 to 3; q is 0 to 4; —A—B— represents —(CH2)r—, —(CH2)t—O—, —(CH2)t—S(═O)u— or —(CH2)t—NR3—; r is 2 to 4; t is 1 to 3; u is 0 to 2; X1 is O, S, NR3 or a direct bond; R1 and R4 are C1-6alkyl, halo, polyhaloC1-6alkyl, hydroxy, mercapto, C1-6alkyloxy, C1-6alkylthio, C1-6alkylcarbonyloxy, aryl, cyano, nitro, Het3, R6, NR7R8 or substituted C1-4alkyl; R2 is aryl, Het1, C3-7cycloalkyl, cyano, optionally substituted C1-6alkyl, —C(═Q)—X2—R15; R3 is hydrogen or C1-4alkyl; R15 is hydrogen, optionally substituted C1-6alkyl, C3-7cycloalkyl, aryl; where X2 is a direct bond, R15 may also be halo or Het1; where X2 is NR5, R15 may also be hydroxy; where X2 is C(═O)—NH—NH or NH—NH—C(&bo

Abstract: This invention provides compounds of formula I,
wherein
R is hydrogen or alkyl of 1-6 carbon atoms;
R′ is hydrogen, alkyl of 1-6 carbon atoms, acyl of 2-7 carbon atoms, or aroyl;
R1, R2, R3, and R4 are each, independently, hydrogen, alkyl of 1-6 carbon atoms, alkoxy of 1-6 carbon atoms, halogen, trifluoroalkyl, —CN, alkyl sulfonamide of 1-6 carbon atoms, alkyl amide of 1-6 carbon atoms, amino, alkylamino of 1-6 carbon atoms, dialkylamino of 1-6 carbon atoms per alkyl moiety, trifluoroalkoxy of 1-6 carbon atoms, acyl of 2-7 carbon atoms, or aroyl;
X is CR5R6 or a carbonyl group;
R5 and R6 are each, independently, hydrogen or alkyl of 1-6 carbon atoms;
or a pharmaceutically acceptable salt thereof, with the proviso that at least one of R1, R2, R3, or R4 are not hydrogen;
which are 5HT2C receptor agonists useful for the treatment of disorders involving the central nervous system such as obsessive-compulsive disorder, depression, anxiety, schizophrenia, migraine, sleep disorde
