The invention relates to a new process for the preparation of compounds of general formula (I) wherein R1 and R2 represent independently hydrogen or C1-6 alkyl with straight or branched chain optionally substituted with aryl group; or C2-7 alkenyl containing 1-3 double bonds; or monocyclic, bicyclic or tricyclic aryl optionally substituted with one or more C1-6 alkoxy, trifiuoro-C1-6 alkoxy, C1-6-alkoxycarbonil, C1-6alkanoyl, aryl, C1-6 alkylthio, halogen or cyano; or optionally substituted monocyclic, bicyclic or tricyclic C3-14 cycloalkyl group; R1 and R2 together with the adjacent nitrogen form a saturated or unsaturated optionally substituted monocyclic or bicyclic heterocyclic ring which may contain further heteroatoms selected from oxygen, nitrogen, or sulphur atoms and hydrochloric acid salts and/or hydrates and/or solvates thereof, by dissolving or suspending trans 4-2-[4-(2,3-dichlorophenyl)-piperazine-1-il]-ethyl}-cyclohexylamine of formula (III) or a salt or a hydrate or a solvate thereof in an inert solvent in the presence of a base then adding a carbonic acid derivative of general formula (VI) wherein R is alkyl with C1-6 straight or branched chain, partially or fully halogenated C1-2 alkyl or phenyl, Z is -O-R or -X, wherein R is as described above, X is halogen, and reacting the compound of general formula (IV) obtained wherein R is as described above, in situ or, optionally in isolated state with an amine of general formula (V) wherein R1 and R2 are as described above to obtain the compound of general formula (I) and then optionally forming the hydrochloride salts and/or hydrates and/or solvates thereof.
该发明涉及一种新的制备通式(I)化合物的过程,其中R1和R2分别独立地表示氢或C1-6直链或支链烷基,可选地被芳基取代;或含有1-3个双键的C2-7烯基;或单环、双环或
三环芳基,可选地被一个或多个C1-6烷氧基、三

硫、卤素或
氰基取代;或可选地取代的单环、双环或
三环C3-14环烷基;R1和R2与相邻的氮一起形成饱和或不饱和的、可选地取代的单环或双环杂环环,该环可以包含进一步从氧、氮或
硫原子选择的杂原子和其
氯化氢盐和/或
水合物和/或溶剂化物,通过将式(III)的转型4-2-[4-(2,3-二
氯苯基)-
哌嗪-1-基]-乙基}-环己基胺或其盐或
水合物或溶剂化物溶解或悬浮在惰性溶剂中,在碱的存在下加入通式(VI)的
碳酸衍
生物,其中R为C1-6直链或支链烷基,部分或完全卤代的C1-2烷基或苯基,Z为-O-R或-X,其中R如上所述,X为卤素,然后在原位或可选地在分离状态下与通式(V)的胺反应,其中R1和R2如上所述,以获得通式(I)的化合物,然后可选地形成其
氯化氢盐和/或
水合物和/或溶剂化物。
