Description
Предлагаемый способ получени 2, 3-дифенил-4- трихлорметил-6-кетотетрагидро -1,3-оксазина заключаетс в том, что р-трихлорметил-р-пропиолактон обрабатывают бензальанилином при температуре 120°С.The proposed method for preparing 2, 3-diphenyl-4-trichloromethyl-6-ketotetrahydro -1,3-oxazine is that p-trichloromethyl-p-propiolactone is treated with benzalaniline at a temperature of 120 ° C.
Пример. Смесь 0,20 г (1,05 моль) трихлорметилпропиолактона и 0,15 г (0,83 моль) бепзальанилина нагревают при 120°С в течение 7 час. После охлаждени реакционную массу перекристаллизовывают из смеси четыреххлористого углерода и гептана.Example. A mixture of 0.20 g (1.05 mol) of trichloromethylpropiolactone and 0.15 g (0.83 mol) of bepsalaniline is heated at 120 ° C for 7 hours. After cooling, the reaction mass is recrystallized from a mixture of carbon tetrachloride and heptane.
Выход целевого продукта 0,22 г (71,8% от теоретического, счита на бензальанилин), температура плавлени 219-22Q°C.The yield of the target product is 0.22 g (71.8% of the theoretical value, calculated as benzalaniline), melting point 219-22Q ° C.
