发明名称 PROCESS FOR PREPARING 2-OXO-1,2,3,4-TETRAHYDRO-PYRIDO(2,3)PYRIMIDIN DERIVATIVES
摘要 Title compds. (I. R1 = pheny1, substituted pheny1; R2 = lower alky1, alkoxycarbony1, aralky1), useful as anaigesics and antiphlogistics, were prepd. by reaction of II and R2X1(X1 = halogen, = ulfonyloxy, ehter residus group), R2(OR2)2 (X2=carbony1,oxary1) or III(X3=diloweralkylamino, lower alkoxy; X4=H, lower alky1). Thus, 0.6 g sodium hydride was added to a mixt. of 3.0 g 1-(m-bromopheny1)- ! 2-oxo-1,2,3,4-tetrahydropyrido[2,3-d pyrimidine and 100 ml DMF and stirred for 30 min, following by addition of 3.5 g propagy1 bromide, and treated at room temp. for 1 hr to give I.
