Claims17
A method for producing a tribenzazepine compound represented by formula (I), which comprises dehydrating a compound represented by formula (II) to produce a compound represented by formula (1):
- wherein Y represent s a hydrogen atom or an alkyl, aryl, acyl, alkoxycarbonyl, aryloxycarbonyl, alkanesulfonyl or arenesulfonyl group;
- R1 and R2 each represents a hydrogen or halogen atom or an alkyl, aryl, hydroxy, alkoxy, aryloxy, acyl, alkoxycarbonyl, aryloxycarbonyl, formyl, carboxyl, sulfo, nitro or amino group;
- R3, R4, R5 and R6 each represents a hydrogen atom or an alkyl or aryl group;
- and m and n each is an integer of from 1 to 4,
- wherein Y, R1, R2, R3, R4, R5, R6, m and n are the same as those in formula (I).
A tribenzazepine compound represented by formula (IV):
- wherein Y1 represents a hydrogen atom or an alkyl, aryl, acyl, alkoxycarbonyl, aryloxycarbonyl, alkanesulfonyl or arenesulfonyl group;
- and R7, R8, R9, and R10 each represents a hydrogen atom or an alkyl group having 10 or less of carbon atoms, with that proviso that all of R7 to R10 are not hydrogen atoms at the same time and that Y1 does not represent a hydrogen atom or an aryl group when R8 is a methyl group and each of R7, R9 and R10 is a hydrogen atom.
A method for producing a compound represented by formula (I), which comprises the following steps:
- reducing a compound represented by formula (III) to produce a compound represented by formula (II);
- and
- dehydrating the compound represented by formula (II) to produce the compound represented by formula (I):
- wherein Y represents a hydrogen atom or an alkyl, aryl, acyl, alkoxycarbonyl, aryloxycarbonyl, alkanesulfonyl or arenesulfonyl group;
- R1 and R2 each represents a hydrogen or halogen atom or an alkyl, aryl, hydroxy, alkoxy, aryloxy, acyl, alkoxycarbonyl, aryloxycarbonyl, formyl, carboxyl, sulfo, nitro or amino group;
- R3, R4, R5 and R6 each represents a hydrogen atom or an alkyl or aryl group;
- and m and n each is an integer of from 1 to 4
- wherein Y, R1, R2, R3, R4, R5, R6, m and n are the same as those in formula (I)
- wherein Y, R1, R2, R3, R4, R5, R6, m and n are the same as those in formula (II).
