где А - Н, ацетил, диалкилфосфонацетил или (диалкилфосфонокси-винил, заключаетс в том, ,что производное фентиазина общей формулыwhere A is H, acetyl, dialkylphosphone acetyl, or (dialkylphosphonoxy-vinyl, is that the fentiazine derivative of the general formula
где R -Н или галоидацетил, подвергают взаимодействию с триалкилфосфитом при нагревании , желательно до 95-160° С с последующим выделением целевого продукта известными приемами.where R is H or haloacetyl, is reacted with trialkylphosphite when heated, preferably up to 95-160 ° C, followed by isolation of the target product by known methods.
Получаемые соединени представл ют собой в зкие жидкости или кристаллические вещества , растворимые в органических растворител х и не растворимые в воде.The resulting compounds are viscous liquids or crystalline substances that are soluble in organic solvents and not soluble in water.
Пример 1. В расплавленный 2-ацетил-10бромацетилфентиазин (3,0 г) через отт нутую на капилл р капельную воронку ввод т лри температуре 150° С и разрежении 100 ил/5г. сг. 2,0 г триэтилфосфита (40% избытка от теории ). Реакционную смесь нагревают 1 час при 150-160° С, затем в вакууме отгон ют избыток фосфита. Прозрачный желтый плав выли-, вают в кристаллизатор. Перекристаллизацией из бензина (100-130° С) получают 2,7 г (76%) 2-ацетил-10-диэтилфосфонацетцлфентиазина с т. пл. 150-160° С.Example 1. In a molten 2-acetyl-10 bromoacetylphenthiazine (3.0 g), the dropping funnel is thrown onto the capillary at a temperature of 150 ° C and a vacuum of 100 Il / 5 g. cr. 2.0 g of triethyl phosphite (40% excess of theory). The reaction mixture is heated for 1 hour at 150-160 ° C, then the excess phosphite is distilled off in vacuum. A clear yellow melt is poured into the mold. By recrystallization from gasoline (100-130 ° C), 2.7 g (76%) of 2-acetyl-10-diethylphosphone acetal-fenthiazine are obtained, with an mp. 150-160 ° C.

Пример 2. Аналогично примеру 1 из 3,0 г 2-ацетил-10-хлорацетилфентиазина и 3,0 г триизобутилфосфита получают 3,5 г (81%) 2-ацетил-10-диизобутилфосфонацетилфентиазина с т. пл. 99-100° С.Example 2. Analogously to example 1, out of 3.0 g of 2-acetyl-10-chloroacetylfenthiazine and 3.0 g of triisobutylphosphite, 3.5 g (81%) of 2-acetyl-10-diisobutylphosphoneacetylfenthiazine are obtained with an mp. 99-100 ° C.
