Description
4eo 604 2 , 2lx~ 1 Aziridinderivatet med formel IV kan framställas endl att] etylenimin omsättes med en nitroetenamin med formeln“» V ~å 'Å Ém°2 ' V ~ ' -1 L'-CNHMe » = (V) ' .E där L' betecknar en avspjälkbar grupp, t.ex. en C1_¿-alkoxigrupp : eller en C1_4-alkyltiogrup, företrädesvis metyltio. Reaktionen kan genomföras i ett lämpligt aprotiskt lösningsmedel, såso aceto- ä nitril. The aziridine derivative of the formula IV can be prepared by reacting the ethyleneimine with a nitroethenamine of the formula '' V ~ å 'Å Ém ° 2' V ~ '-1 L'-CNHMe »= (V)'. E where L 'represents a leaving group, e.g. a C 1-4 alkoxy group: or a C 1-4 alkylthio group, preferably methylthio. The reaction can be carried out in a suitable aprotic solvent, such as acetonitrile.
Uppfinningen illustreras genom följande exempel. Exempel 1 illustrerar framställning av den nya förneingen enligt uppfin- ningen, och exempel 2 illustrerar användning av denna förening för framställning av ranitidin.The invention is illustrated by the following examples. Example 1 illustrates the preparation of the novel compound of the invention, and Example 2 illustrates the use of this compound for the preparation of ranitidine.
Exempel 1. N-metyl-a-(nitrometylen)-1-aziridinmetanamin.Example 1. N-methyl-α- (nitromethylene) -1-aziridinemethanamine.
En lösning av 0,47 g etylenimin och 1,48 g N-metyl-(1-metyl- tio)-2-nitroetenamin i S ml acetonitril omrördes vid rumstemperatur under 2 dygn. Den resulterande suspensionen indunstades i vakuum vid rumstemperatur, och återstoden extraherades med 100 ml varmt etylacetat. Extraktet indunstades i vakuum, och återstoden sus- penderades i S0 ml etylacetat, varpå den resulterande suspensionen filtrerades. Filtratet indunstades till en volym av ca 5 ml och kromatograferades på kiseldioxid med användning av etylacetat så- som elueringsmede1.' Man indunstades i vakuum det eluat, vilket gav ett Rf-värde av 0,28 vid tunnskiktskromatografi på kiseldioxid med användning av etylacetat såsom elueringsmedel. Härvid erhölls 0,33 g av titelföreningen med en smältpunkt av 118-119°C.A solution of 0.47 g of ethyleneimine and 1.48 g of N-methyl- (1-methylthio) -2-nitroethenamine in 5 ml of acetonitrile was stirred at room temperature for 2 days. The resulting suspension was evaporated in vacuo at room temperature, and the residue was extracted with 100 ml of hot ethyl acetate. The extract was evaporated in vacuo, and the residue was suspended in 50 ml of ethyl acetate, after which the resulting suspension was filtered. The filtrate was evaporated to a volume of about 5 ml and chromatographed on silica using ethyl acetate as eluent. The eluate was evaporated in vacuo to give an Rf value of 0.28 by thin layer chromatography on silica using ethyl acetate as eluent. This gave 0.33 g of the title compound, m.p. 118-119 ° C.
Exempel 2. N-[2-[ZS-Lïdimetylamino)metyl]-2-furanylmetyl]- tiqfetylf-N'-metyl-2-nitro-1,1-etendiamin. A Till en blandning av 0,156 g 5-L(dimetylamino)metyl]-2-furan- metantiol-oxalat (1:1), 0,05 g natriumditionit och 0,15 g vatten- fritt natriumkarbonat i 0,4 ml vatten sattes 15 ml eter och ett överskott av vattenfritt natriumkarbonat. Den resulterande bland- ningen filtrerades, och filtratet indunstades i vakuum. Till åter- stoden sattes 0,072 g N-metyl-u-(nitrometylen)-1-aziridinmetan- amin och 2 ml metanol, och den erhållna lösningen indunstades till torrhet. återstoden upphettades vid 98-100°C under 1,25 timar, och produkten kromatograferades på kiseldioxid, varvid man såsom elueringsmedel använde en blandning av metanol och 0,88 amoniak i volymförhållandet 79:1. bet lämplga eluatet indunstades i va- kuum, varvid man erhöll 0,113 g av titelföreningen med en smält-Example 2. N- [2- [2S-Lidimethylamino) methyl] -2-furanylmethyl] -phetyl [N'-methyl-2-nitro-1,1-ethenediamine. To a mixture of 0.156 g of 5-L (dimethylamino) methyl] -2-furan-methanethiol oxalate (1: 1), 0.05 g of sodium dithionite and 0.15 g of anhydrous sodium carbonate in 0.4 ml of water was added 15 ml of ether and an excess of anhydrous sodium carbonate. The resulting mixture was filtered, and the filtrate was evaporated in vacuo. To the residue were added 0.072 g of N-methyl-u- (nitromethylene) -1-aziridinemethanamine and 2 ml of methanol, and the resulting solution was evaporated to dryness. the residue was heated at 98-100 ° C for 1.25 hours, and the product was chromatographed on silica using a mixture of methanol and 0.88 ammonia in a volume ratio of 79: 1 as eluent. The appropriate eluate was evaporated in vacuo to give 0.113 g of the title compound with a melting point.
