Hoca. 2НС1
который может быть использован в ка честве бронхорасшир ющего средства.
Целью изобретени вл етс упрощение процесса получени хлоргидра- та пирбутерола.
Пример 1. Получение пирбутерола дигидрохлорида.
Раствор 5-гидрокси-2-(1-гидрок- си-2- трет-бутиламинозтил)-пиридина
217253 2
(и,5иО г, 0,00238 моль) в 5 мл вод- ного 38%-ного раствора формальдегида и 1 мл триэтиламина нагревают 8 ч при температуре кипени с об- 5 ратным холодильником. Добавл ют еще 5 мл водного раствора формальдегида и нагревание при температуре кипени с обратным холодильником продолжают в течение 6 ч. Растворители 10 отгон ют в вакууме с получением неочищенного продукта, который выдел ют растворением в минимальном объеме холодного метанола и насыщением холодного раствора сухим хло- 15 ристым водородом с получением 0,52 г (70%) пирбутерола дигидрохлорида, т.пл. С (с разложением).
