Description
Przedmiotem wynalazku jest sposób wytwarza¬ nia nowych pochodnych l,4-benzodwuazepinonu-2 o ogólnym wzorze 1, w którym Rx oznacza grupe karbometoksylowa lub benzoilowa, a R2 oznacza atoim chlorowca.The invention relates to a manufacturing process new derivatives of 1,4-benzodiazepinone-2 of general formula I wherein R x is a group carbomethoxy or benzoyl and R2 is atoim of halogen.
Sposób wedlug wynalazku polega na tym, ze na zwiazek o ogólnym wzorze 2, w którym Rt i R2 maja wyzej podane znaczenie dziala sie szescio- metylenoczteroamina. Reakcje wg wynalazku pro¬ wadzi sie w srodowisku, alkoholu lub wodnego roztworu alkoholu, korzystnie etanolu, w podwyz¬ szonej temperaturze, na przyklad w temperaturze wrzenia mieszaniny pod chlodnica zwrotna.The method according to the invention consists in the following: a compound of general formula II, wherein Rt and R2 have the meaning given above, there are six methylene tetramine. The reactions according to the invention are pro-moted works in the environment, alcohol or water alcohol, preferably ethanol, solution in elevation temperature, for example at temperature the mixture is boiling under a reflux condenser.
Nowe zwiazki o wzorze ogólnym i w badaniach farmakologicznych wykazuja dzialanie na central¬ ny uklad nerwowy. Szczególnie korzystne wlasci¬ wosci farmakologiczne wykazuja zwiazki o wzorze 1, w którym R± oznacza grupe benzoilowa, a R2 atom chloru lub bromu.New compounds with general formula and in research pharmacological evidence shows an effect on the central new nervous system. Particularly advantageous properties The pharmacological properties are shown by the compounds of formula Is a benzoyl group and R2 chlorine or bromine.
Zwiazki wyjsciowe do syntezy o ogólnym wzorze 2, w którym Rt i R2 maja wyzej podane znaczenie otrzymuje sie przez reakcje 4,5-dwu- poosjtawaonych pochodnych O-aiminoibenzocfenonu z halogenkiem halogenoacetylu.Starting compounds for general synthesis Formula 2, wherein Rt and R2 are as defined above the meaning is obtained by reactions 4,5-double- poositava derivatives of O-aiminoibenzocphenone with a haloacetyl halide.
Ponizsze przyklady ilustruja sposób wedlug wy¬ nalazku.The following examples illustrate the method according to invention.
Przyklad I. 0,5 g (0,0013 mola) 2-chloroaceta- mido-4-karbome(toiksy-5-chloiroibenzofenonu i 0,21 g (0,0015 mola) szesciometylanoczteroaminy w 5 ml etanolu ogrzewa sie pod chlodnica zwrotna w ciagu 30 godzin. Nastepnie z miesza¬ niny reakcyjnej oddestylowalje sie etanol, a po¬ zostalosc miesza sie z woda, saczy i suszy pod zmniejszonym cisnieniem. Otrzymuje sie 0,5 g surowego 7-chloro-8^karbometoksy-l,3^dwuwodo- ro-2H-5-fenylo-l,4-foenzodwaiazepinonu-2. Z suro¬ wego produktu po krystalizacji z benzenu otrzy¬ muje sie 0,25 g czystego zwiazku o temperaturze topnienia 229—231°C. Wydajnosc 61% wydajnosci teoretycznej.Example I. 0.5 g (0.0013 mol) of 2-chloroaceta- mido-4-carbome (toix-5-chloiroibenzophenone and 0.21 g (0.0015 mol) hexamethylanetetraamine in 5 ml ethanol is heated to a reflux condenser within 30 hours. Then with the mix In the reaction mixture, ethanol was distilled off, and then the the leftover is mixed with water, sipped and dried under reduced pressure. 0.5 g is obtained crude 7-chloro-8-carbomethoxy-1,3-dihydrate ro-2H-5-phenyl-1,4-foenzodwaiazepinone-2. With raw of the product obtained after crystallization from benzene 0.25 g of pure compound at temperature is mixed mp 229-231 ° C. Efficiency 61% yield theoretical.
Przyklad II. 1,0 g (0,0024 mola) 2-chloroace- tamido-4-benzoilo-5-chlorofoanzofenonu i 0,42 g (0,003 mola) szesciometylenoczteroaiminy w 10 ml. 95% etanolowo^wodnego roztworu ogrzewa sie pod chlodnica zwrotna w ciagu 30 godzin. Po zakoncze¬ niu reakcji odparowuje sie rozpuszczalnik, a pozo¬ stalosc miesza sie z woda. Wytworzony osad saczy sie i suszy pod zmniejszonym cisnieniem. Suchy surowy produkt poddaje sie krystalizacji z ben¬ zenu. Otrzymuje sie 0,4 g 7-chloro-8-beinzoilo-l,3- Hdwuwodoro-2H^5-fenylo^l,4-benzodwuazepinonu-!2, o temperaturze topnienia 260—262°C. Wydajnosc procesu 40% wydajnosci teoretycznej.Example II. 1.0 g (0.0024 mol) of 2-chloroac- tamido-4-benzoyl-5-chlorophosphenone and 0.42 g (0.003 mol) hexamethylene tetraimine in 10 ml. A 95% ethanolic aqueous solution is heated under reflux condenser within 30 hours. After it finished During the reaction, the solvent is evaporated off and the remainder of the mixture constancy mixes with water. A sack sediment formed and dried under reduced pressure. Dry the crude product is crystallized from petrol zenu. 0.4 g of 7-chloro-8-benzoyl-1,3- Hdihydro-2H ^ 5-phenyl ^ 1,4-benzodiazepinone-! 2, mp 260-262 ° C. Performance process 40% of theoretical efficiency.
