Description
трехфтористого бора при комнатной температуре, и реакцию ведут 2ч. Выпавший осадок промывают холодным метанолом и получают 65 мг циклического тиоацетал 1-диметиламиносульфонил-2-амино-5 (6)-(дитиолан-2-ил)-бензимидазола . Промывные воды и фильтраты соедин ют и смешивают с 20 мл насыщенного раствора карбоната натри . Водный раствор экстрагируют этилацетатом. Экстракт промывают насыщенным раствором хлористого натри и сушат над сульфатом магни , Этилацетат отгон ют досуха в вакууме. Твердый остаток обрабатывают метанолом и нерастворимый в метаноле осадок собирают. Выход 155 мг. Метанольный фильтрат выпаривают досуха в вакууме и получаот еще 55 мг целевого продукта, м/е 344.
Пример 2. 1-диметиламиносульфонил-2-амино-5 (6)-(1,5-дитиола-2-ил )-бензимидазол.
220 мг (0,6 ммол ) 1-диметиламиносульфонил-2-амино-5 (6)-формилбензимидазола , 2 мл метанола, 0,15 мл (1,6 ммол ) 1,3-пропандитиола и 0,75 мл эфирата трехфтористого бора смешивают при комнатной температуре К смеси прибавл ют примерно 6 мл диэтилового эфира, провод т реакцию 2 ч. Реакционную смесь разбавл ют до объема 12 мл диэтиловым эфиром и выпаривают осадок, центрифугируют И верхний слой жидкости декантируют Осадок суспендируют в диэтиловом эфире и смесь снова центрифугируют. Верхний слой жидкости декантируют и твердый продукт сушат в вакууме. .Выход 224 мг (75%) циклического тиоацетал , 1-диметиламиносульфонил-2-амино-5 (6)-(1,5-дитиолан-2-ил)-бензимидазола , т/е. 358.
