Oheisen keksinnön kohteena on 2-isopropvyliaminopyrimidiinin valmistusmenetelmä, jonka etuna on yksivaiheinen reaktio, jonka saanto on suurempi kuin aikaisemmin tunnetuilla menetelmillä, joissa 2-isopropyyliaminopyrimidiiniä valmistetaan 2-aminopyrimidiinistä.
On myös tunnettua valmistaa 2-isopropyyliaminopvrimidiiniä 2-klooripyrimidiinistä ja isopropyyliamiinista; tätä ovat kuvanneet Brown D.J. ja Harper J.S. J. Chem. Soc. 5542 (1965).
Vain yksi pelkistävä alkylointi - tekijöiden mukaan - näyttää tulleen suoritetuksi 2-alkyyliaminopyrimidiinin valmistamiseksi 2-aminopyrimidiinistä käyttämällä muurahaishappoa; kts. I.A. Kaye ja I.C. Kogon Rec. Trav. Chim. 71, 309 (1952).
2-isopropyyliaminopyrimidiiniä voidaan valmistaa myös alkyloimalla 2-aminopyrimidiini alkyylihalogenidilla, jolloin saadaan 2-alkyyli- 1,2-dihydro-2-iminopyrimidiinejä, jotka emäksisissä olosuhteissa muuttuvat vastaaviksi 2-alkyyliaminopyrimidiineiksi Dimroth'in toisiintumisen kautta (Brown D.J. ja Paddon-Row M.N.J. Chem. Soc.
(C) 903 (1967). Kaikilla näillä tunnetuilla menetelmillä saadan kuitenkin yleisesti 2-isopropyy1iaminopyrimidiiniä huonolla saanolla, alle 50 %.
2 68620
Oheisen keksinnön mukaisesti 2-isopropyyliaminopyrjmidiiniä voidaan saada erittäin hyvällä saannolla saattamalla 2-aminopyrimidiini reagoimaan asetonissa orgaanisen karboksyylihapon ja aikaiimetalli-boorihydridin ylimäärän läsnäollessa. Asetoni on tässä reaktiossa sekä reagenssi että liuotin? asetonia tarvitaan siten suuri ylimäärä.
Seuraava esimerkki selventää keksintöä paremmin: 2 litran reaktoriin, joka on varustettu sekoitus-, lämmitys- ja jäähdytyslaitteilla, kaadetaan liuos, joka sisältää 9,5 g (0,1 moolia) 2-aminopyrimidiiniä 100 mlrssa vedetöntä asetonia ja 100 ml kiteytyvää etikkahappoa; reaktioseosta pidetään huoneen lämpötilassa tai parhaiten muutama aste sen alapuolella.
Liuokseen lisätään hitaasti ja samalla sekoittaen ja pitämällä lämpötila samalla alueella 10 g (0,26 moolia) natriumboorihydridiä. Sekoittamista jatketaan huoneen lämpötilassa 5 tuntia lisäyksen jälkeen.
Tämän jälkeen lisätään 150 ml 20 %:sta vesipitoista ammoniakki liuosta pitäen lämpötila noin 30°C:ssa. Lisätään 100 ml kloroformia ja tämän jälkeen 50 ml vettä. Lakataan sekoittamasta, jolloin saadaan kaksifaasinen liuos. Kloroformifaasi erotetaan ja vesiliuos pestään kaksi kertaa 100 ml:lla kloroformia. Kaikki kloroformifaasit kerätään yhteen, pestään vesipitoisella ammoniakkiliuoksella ja sen jälkeen vedellä neutraaliksi. Tämän jälkeen kuivataan natrium-sulfaatilla.
Analyysin perusteella saadaan 4 g (saanto 60 %) erittäin puhdasta 2-isopropyy1i am i nopy rimidiiniä.
