Abstract
1. Кислотно-аддитивная соль производного пирролопиримидинoна, представленного следующей формулой (1), ! ! которую выбирают из гентизатной, малеатной, цитратной, фумаратной и полутартратной солей. ! 2. Способ получения кислотно-аддитивной соли производного пирролопиримидинoна взаимодействием производного пирролопиримидинoна, представленного следующей формулой (1) ! ! с фармацевтически приемлемой кислотой, выбранной из гентизиновой кислоты, малеиновой кислоты, лимонной кислоты, фумаровой кислоты и винной кислоты. ! 3. Способ по п.2, который включает: ! растворение или суспендирование фармацевтически приемлемой кислоты, выбранной из гентизиновой кислоты, малеиновой кислоты, лимонной кислоты, фумаровой кислоты и винной кислоты с получением раствора кислоты; ! смешение производного пирролопиримидинoна, представленного вышеуказанной формулой (1), с раствором кислоты; и ! фильтрование, промывку и сушку твердого вещества, полученного путем перемешивания вышеупомянутой смеси, с получением кристаллической кислотно-аддитивной соли. ! 4. Способ по п.3, где концентрация кислоты в растворе кислоты составляет от 1 до 30 мас.%. ! 5. Способ по п.3 или 4, где растворителем, используемым для растворения или суспендирования кислоты, является один растворитель, выбранный из группы, состоящей из воды, ацетона, метанола, этанола, изопропанола и ацетонитрила или их смешанный растворитель. ! 6. Способ по п.2 или 3, где кислоту используют в количестве от 0,5 до 3,0 эквивалентов по отношению к производному пирролопиримидинoна, представленного формулой (1). ! 7. Способ по п.2 или 3, где реакцию проводят при температуре от -30 до 50°C. ! 8. Способ по п.2 или 1. The acid addition salt of the pyrrolopyrimidinone derivative represented by the following formula (1),! ! which is selected from gentisate, maleate, citrate, fumarate and semi-tartrate salts. ! 2. A method for producing an acid addition salt of a pyrrolopyrimidinone derivative by reacting a pyrrolopyrimidinone derivative represented by the following formula (1)! ! with a pharmaceutically acceptable acid selected from gentisic acid, maleic acid, citric acid, fumaric acid and tartaric acid. ! 3. The method according to claim 2, which includes:! dissolving or suspending a pharmaceutically acceptable acid selected from gentisic acid, maleic acid, citric acid, fumaric acid and tartaric acid to obtain an acid solution; ! mixing a pyrrolopyrimidinone derivative represented by the above formula (1) with an acid solution; and! filtering, washing and drying a solid obtained by stirring the above mixture to obtain a crystalline acid addition salt. ! 4. The method according to claim 3, where the concentration of acid in the acid solution is from 1 to 30 wt.%. ! 5. The method according to claim 3 or 4, where the solvent used to dissolve or suspend the acid is one solvent selected from the group consisting of water, acetone, methanol, ethanol, isopropanol and acetonitrile or a mixed solvent thereof. ! 6. The method according to claim 2 or 3, where the acid is used in an amount of from 0.5 to 3.0 equivalents with respect to the pyrrolopyrimidinone derivative represented by the formula (1). ! 7. The method according to claim 2 or 3, where the reaction is carried out at a temperature of from -30 to 50 ° C. ! 8. The method according to claim 2 or
