Description
Изобретение относитс к способу получени медицинского препарата - цетамифена, представл ющего собой аминоэтаноловую соль фенилэтилуксусной кислоты.The invention relates to a method for producing a medical preparation, cetamifen, which is an aminoethanol salt of phenylethyl acetic acid.
Цетамифен обладает гипохолестеринемическим действие.м, оказывает также умеренный гипотензивный эффект, малотоксичен.Cetamiphen has a hypocholesterolemic effect. M, also has a moderate hypotensive effect, low toxicity.
Известен способ получени аминоэтаноловой соли фенилэтилуксусной кислоты (цетамифена ), заключающийс во взаимодействии фенилэтилуксусной кислоты и моноэтаноламила в среде бензола.A known method for the preparation of the aminoethanol salt of phenylethyl acetic acid (cetamiphene) involves the interaction of phenylethyl acetic acid and monoethanolamyl in a benzene medium.
Дл увеличени выхода целевого продукта предложен способ получени аминоэтаноловой соли фенилэтилуксусной кислоты, заключающийс во взаимодействии фенилэтилуксусной кислоты и моноэтаноламина в среде абсолютного изопропилощого спирта. Выход целевого продукта 80% от теоретического.In order to increase the yield of the target product, a method has been proposed for the preparation of the aminoethanol salt of phenylethyl acetic acid, which consists in the interaction of phenylethyl acetic acid and monoethanolamine in an environment of absolute isopropyl alcohol. The yield of the target product 80% of theoretical.
Пример. В стальной эмалированный аппарат с мещалкой, обратным холодильником, рубащкой дл обогрева паром и охлаждени водой загружают абсолютный изопропиловый спирт и фенилэтилуксусную кислоту в соотнощении 2-: 1. К раствору фенилэтилуксусной 4Example. Absolute isopropyl alcohol and phenylethyl acetic acid are added to a steel enamelled apparatus with a mechalka, a reflux condenser, a jacket for heating with steam and cooling with water in a 2-: 1 ratio. To a solution of phenylethylacetic 4
кислоты при работающей мещалке приливают эквимолекул рное количество моноэтаноламина . Дл полноты реакции смесь выдерживают при размещивании в течение 4 час. Затем реакционную массу нагревают до 63-65°С и фильтруют через воронку дл гор чей фильтрации в сборник.Acids with a running broom make equimolecular amount of monoethanolamine. For completeness of the reaction, the mixture was incubated for 4 hours. Then the reaction mass is heated to 63-65 ° C and filtered through a funnel for hot filtration into a collector.
После охлаждени выпавщие кристаллы цетамифена отжимают на нутч-фильтре, промывают абсолютным изопропнловым спиртом и сущат при 35-45°С. Выход цетамифена 80% от теоретического.After cooling, precipitated crystals of cetamiphen are squeezed out on a suction filter, washed with absolute isopropyl alcohol and present at 35-45 ° C. The yield of cetamiphen 80% of theoretical.
Предмет изобретени Subject invention
Способ получени аминоэтаноловой соли фенилэтилуксусной кислоты взаимодействием фенилэтилуксусной кислоты с моиоэтаноламииом в среде органического растворител , отличающийс тем, что, с целью увеличени выхода целевого продукта и упрощени процесса , в качестве растворител используют абсолютный изопропиловый сцирт.A method of producing aminoethanol salt of phenylethyl acetic acid by reacting phenylethyl acetic acid with myoethanolamia in an organic solvent, characterized in that, in order to increase the yield of the target product and simplify the process, absolute isopropyl citrate is used as solvent.
