.чаетс  в том, что соединение общей формулы
Ar.vx-
::1т:.
Аг.
где Аг;| и Ar,j имеют вышеуказанные значени , подвергают взаимодействию с перекисью водорода или перйодатом.
Пример 1. 2г 5,6-ди-п-метоксифенил-2 ,3-дигидро-4Н-имидаэо f2, тиазола суспендируют в 33 мл этилового спирта и приготовленную суспензию смешивают в течение 5 мин с 7,01 МП 30%-ного раствора перекиси водорода. Реакционную смесь выдерживают в течение 90 мин при температуре ее кипени  с обратным холодильником . Затем реакционную смесь охлаждают, выливают ее в 20 мл воды со льдом и производ т экстрагировани этиловым эфиром уксусной кислоты. Из состава полученного после упаривани  экстракта, промытого водой и высушенного сернокислым натрием, получают после перекристаллизации 5,б-ди-п-метоксифенилимидазо 2 ,,3-дигидротиазолсульфоксид , т.пл. 1761770с .
Исходный материал может быть получен следующим образом,
2,5 г натри  раствор ют в 220 мл этилового спирта. К полученному раствору прибавл ют 35 г 4,5-дианизилимидазолин-2-тиона . Получают суспензию . В течение 2 мин к этой суспензи прибавл ют по капл м при комнатной температуре (перемешивают) 15,7 мл 2-хлорэтанола. Реакционную смесь перемешивают в течение 1 ч при 609С и затем в течение 4 ч при температуре кипени  с обратным холодильником. Непосредственно после этого слабую суспензию упаривают досуха. Остаток подвергают очистке при помощи ацетона/воды . Получают 4,5-ди-(п-метокс фенил) -2 -|Ь-оксиэтилмеркаптоимидазол.
14,8 г 4,5-ди-(п-метоксифенил)-2-l -oкcиэтилмepкaптoимидaзoлa раствор ют в 50 мл абсолютного пиридина и при перемешивании и температуре приблизительно внутри реакционного сосуда к раствору прибавл ют по капл м 15,8 г бензолсульфохлорида в 60 мл абсолютного пиридина. Непосредственно после этого реакционную смесь перемешивают в течение 60 ч. при температуре 0°С. Затем реакционную смесь выливают в воду со льдом и производ т экстрагирование дихлорметаном . Объединенные и промытые водой три раза дихлорметановые экстракты сушат сернокислым натрием и эатем упаривают досуха. В зкий маслообразный продукт кристаллизуют из смеси
толуола и петролейного эфира. Полу- ченный указанным способом 5,6-ди- (п-метоксифенил)-имидазо 2,1-Ь -дигидротиазол имеет т.пл. 152-154с.
Пример 2. 0,5 г 5,6-ди-п-метоксифенил-2 ,3-дигидро-4Н-имидазо 12,1-Ь тиазола суспендируют в 1,5 мл лед ной уксусной кислоты и приготовленную суспензию смешивают с 0,9 мл 30%-ного раствора перекиси водорода. Реакционную смесь перемешивают в течение 7 ч при , затем выливают ее в воду со льдом и производ т экстрагирование этиловым эфиром уксусной кислоты. Органическую фазу промывают 1 н. раствором гидроокиси натри  до тех пор, пока экстракт не становитс  основным. После этого органическую фазу промывают водой и раствором соли до нейтральной реакции промывных вод, сушат сернокислым натрием и затем упаривают. Остаток кристаллизуют из этилового эфира уксусной кислоты, после чего полученный продукт перекристаллизовывают из смеси этилового эфира уксусной кислоты и петролейного эфира.
В результате получают 5,6-ди-пметоксифенилимидазо 2,1-Ь}-дигидротиазолсульфона с т .пл. 186-1870С. Аношогичным образом получают: 6-(п-метоксифенил )-5-.(4-пиридил )-2, 3-дигидро-имидазо 2 ,1-ь тиазолсульфоксид , т.пл. 165-170С, 6-(п-фторфенил )-5-4-пиридил-2,3-дигидро-имидазо 2,1-Ь тиазолсульфоксид, т.пл. 229231 С , 5,6-ди- (2-пиридил)-2, 3-дигидро-имидазо 2 ,1-Ь тиазолсульфоксид, т.пл. 199-2000С.
