Изобретение относитс к способу получени нового соединени , которое может найти применение в фармацевтической промышленности .This invention relates to a process for the preparation of a novel compound that can be used in the pharmaceutical industry.
Широко известен способ получени тиоэфиров из меракаптидов натри или кали и алкилирующих агентов.A method of producing thioesters from sodium or potassium meracaptids and alkylating agents is widely known.
Использование известного способа привело к получению 5-дезокси-5-фтор-6-метилмеркаптопуринрибозида формулы:Using a known method resulted in a 5-deoxy-5-fluoro-6-methylmercaptopurine riboside formula:
ОН ОНOH OH
обладающего ценной биологической активностью .possessing valuable biological activity.
Способ заключаетс в том, что 5-дезокси-5фтор-2 ,3-ди-0 - диацетил-6-меркаитопуринрибозид подвергают взаимодействию с йодистым метилом в щелочной среде с последующим выделением целевого продукта известным способом . При этом во врем реакции метилировани происходит одновременное отщепление обеих ацетильных групп радикала рибозида. Пример. 210 мг 6-меркапто-9-(2,3-диацетил-5-дезокси - 5 - фтор- (3-D - рибофуранозил )-пурина раствор ют в 2,5 мл метанола и воды (соотнощение 2: 1) и провод т реакцию между полученной смесью и 1,07 мл йодистого метила. Затем в смесь по капл м добавл ют 0,554 мл NaOH и в течение часа перемешивают при комнатной температуре, после чего обрабатывают уксусной кислотой до рН 5. Затем раствор концентрируют в вакууме до сухого состо ни .The method consists in that 5-deoxy-5-fluoro-2, 3-di-0-diacetyl-6-merkaitopurinriboside is reacted with methyl iodide in an alkaline medium, followed by isolation of the target product in a known manner. In this case, during the methylation reaction, both acetyl groups of the riboside radical are simultaneously cleaved. Example. 210 mg of 6-mercapto-9- (2,3-diacetyl-5-deoxy-5-fluoro- (3-D-ribofuranosyl) -purine) is dissolved in 2.5 ml of methanol and water (ratio 2: 1) and wire The reaction between the mixture obtained and 1.07 ml of methyl iodide is then added dropwise to the mixture 0.554 ml of NaOH and stirred for an hour at room temperature, then treated with acetic acid to pH 5. The solution is then concentrated in vacuo to dryness. neither
Полученный продукт очищают на колонке силикагел (100 г), использу в качестве растворител смесь хлороформа и 96%-ного этанола (соотношение 9:1). В результате получают 152 мг (89% теории) стекловидного продукта , из которого после выдерживани в эфире выпадают кристаллы. После сушки в вакууме при 75°С, т. пл. полученного продукта составл ет 163-164°С. Путем перекристаллизации из метанола т. пл. можно повысить до 164-165°С. +173,5 (с 1,2 воды), ультрафиолетовый спектр (метанол) Ямакс. 282,5 и 217,5 nm, плечо при 291 nm, 243 пш. 34The product obtained is purified on a silica gel column (100 g) using a mixture of chloroform and 96% ethanol (9: 1 ratio) as a solvent. As a result, 152 mg (89% of theory) of a vitreous product are obtained, from which crystals are left to stand in the ether. After drying in vacuum at 75 ° C, so pl. the resulting product is 163-164 ° C. By recrystallization from methanol, m.p. can be increased to 164-165 ° C. +173.5 (with 1.2 water), ultraviolet spectrum (methanol) Yamax. 282.5 and 217.5 nm, shoulder at 291 nm, 243 psh. 34
