The simple, new, original and convenient for use, procedure for obtaining of compounds, belonging to the group of $i(heterocyclic aminoalkyl benzamides) of general formula 1, is developed, and/or salts and/or hydrates and/or optical isomers thereof, wherein R1 and R2 denote C1-C4 $i(alkyl) group, R3 denotes an $i(aminosulphonyl) group, denotes a $i(hydrogen) atom or an $i(amino) group, R5 denotes a $i(hydrogen) or a $i(halogen) atom, and and the coefficients $i(m )and $i(n) have value of 1 and/or 2. Of a particular interest in clinical practice are: $i(sulpiride )(RS, R+ or S-)-(5-$i(aminosulphonyl))-N-/(1-$i(ethyl)-2-$i(pyrrolidinyl))$i(methyl)/-2-$i(methoxybenzamide)) and sulmepride (RS, R+ or S-)-(5-($i(aminosulphonyl))-2-$i(methoxy)-N-/-(1-$i(methyl-)2-$i(pyrrolidinyl)methyl/benzamide)). The compounds belonging to this group are used in therapy as: antipsychotics, anti depressives and anti emetics, fungicides, for contraceptive mixtures, in treatment of sterility, as radiopharmaceutical compositions in nuclear medicine, in treatment of migraine of various origins, as well as in treatment of parkinsonism. The advantage of the present invention is in its completely new and simple way to carry out the synthesis of $i(heterocyclic aminoalkyl benzamides )and/or salts and/or hydrates thereof, through reaction of $i(2-alcoxy-5-suiphamoyl-alkyl benzoate )with the corresponding (RS R+ or S-) heterocyclic amine. )Lower temperature of rection and work at atmospheric pressure without catalysts, performing the reaction in cheaper and safer organic solvents, i obtaining the final product which does not require any additional purification, achieving of I good yield and high quality of the final product, cheaper procedure for industrial use and obtaining of the product of high pharmacopeic purity.
一种简单、新颖、原创且方便使用的程序,用于获取属于$i(杂环氨基烷基苯甲酰胺)一般式1组化合物,以及/或其盐和/或水合物和/或其光学异构体,其中R1和R2表示C1-C4的$i(烷基)基团,R3表示$i(氨基磺酰基)基团,表示$i(氢)原子或$i(氨基)基团,R5表示$i(氢)或$i(卤素)原子,系数$i(m)和$i(n)的值为1和/或2。在临床实践中特别感兴趣的是:$i(舒必利)(RS、R+或S-)-(5-$i(氨基磺酰基))-N-/(1-$i(乙基)-2-$i(吡咯烷基))$i(甲基)/-2-$i(甲氧基苯甲酰胺)和舒美必利(RS、R+或S-)-(5-($i(氨基磺酰基))-2-$i(甲氧基)-N-/-(1-$i(甲基-)2-$i(吡咯烷基)甲基/苯甲酰胺)。属于该组的化合物在治疗中用作:抗精神病药、抗抑郁药和抗恶心药、杀菌剂、避孕混合物、治疗不育症、核医学中的放射性药物组合物、治疗各种起源的偏头痛以及治疗帕金森病。本发明的优点在于通过$i(2-烷氧基-5-磺酰基烷基苯甲酸酯)与相应的(RS R+或S-)杂环胺反应,以完全新的简单方式合成$i(杂环氨基烷基苯甲酰胺)和/或其盐和/或水合物,反应温度较低,在大气压下无需催化剂,在更便宜、更安全的有机溶剂中进行反应,获得不需要任何额外纯化的最终产品,实现良好的产率和高品质的最终产品,更便宜的工业用程序和高药典纯度的产品。
