On January 31, 1985, Levkovskaya, L. G.; Sazonov, N. V.; Grineva, N. A.; Mamaeva, I. E.; Serochkina, L. A.; Safonova, T. S. published an article.COA of Formula: C9H13ClN4 The title of the article was Study of nitrogen- and oxygen-containing heterocycles. 42. Pyrimido[4,5-b]- and pyrido[2,3-b]-1,4-benzoxazepines. And the article contained the following:
Oxazepines I (R = H, Cl, R1X = N, CH, ClCH, R2 = NHCH2Ph, NHPh, piperidino, morpholino, NH2, Cl, OH, 1-methylpiperazinyl, H) were prepared in 25-95% yields by cyclocondensation of pyridines or pyrimidines II wiwth 5,2-R3YC6H3CHO in DMF containing NaH. Reduction of I by NaBH4 in absolute EtOH gave 76-100% of the corresponding 5,6-dihydro derivatives The experimental process involved the reaction of 4-Chloro-6-(piperidin-1-yl)pyrimidin-5-amine(cas: 84762-70-9).COA of Formula: C9H13ClN4
The Article related to benzopyridooxazepine, benzopyrimidooxazepine, pyridooxazepine benzo, pyrimidooxazepine, oxazepine pyrido pyrimido, Heterocyclic Compounds (More Than One Hetero Atom): Other 7-Membered Rings and other aspects.COA of Formula: C9H13ClN4
