Abstract

Wynalazek ujawnia 4-metylo-7-(propan-2-ylo)-l,5,6,7-tetrahydro-2H-azepino-2-on o wzorze 1 znajdujący zastosowanie jako substrat do dalszych syntez w przemyśle farmaceutycznym. Wynalazek dotyczy również sposobu otrzymywania 4-metylo-7-(propan-2-ylo)-l,5,6,7-tetrahydro-2H-azepino-2-on o wzorze l, który polega na tym, że 1g oksymu piperytonu o wzorze 2 i rozpuszcza się w roztworze 0,6g NaOH, 5 ml H2O i 4 ml tetrahydrofuranu, po czym całość ochładza się do 5°C i przy intensywnym mieszaniu wkrapla się l,82g TsCl w 2 ml tetrahydrofuranu, a reakcję prowadzi się przez 19 h w temperaturze pokojowej. Następnie mieszaninę ogrzewa się przez 2h w temperaturze 50°C przy ciągłym mieszaniu, całość rozcieńcza się wodą do 100 ml i ekstrahuje się eterem dietylowym.The invention discloses 4-methyl-7- (propan-2-yl) -1, 5,6,7-tetrahydro-2H-azepin-2-one of formula 1 which is used as a substrate for further syntheses in the pharmaceutical industry. The invention also relates to a method for preparing 4-methyl-7- (propan-2-yl) -1, 5,6,7-tetrahydro-2H-azepin-2-one of formula I, which consists in that 1g of piperitone oxime formula 2 and dissolved in a solution of 0.6g NaOH, 5 ml H2O and 4 ml tetrahydrofuran, after which it is cooled to 5 ° C and 1.82g TsCl in 2 ml tetrahydrofuran is added dropwise with vigorous stirring, and the reaction is carried out for 19 h at room temperature. The mixture is then heated for 2h at 50 ° C with continuous stirring, the whole is diluted with water to 100 ml and extracted with diethyl ether.
