Reaction of 2-bromo-7-methyl-5-oxo-5H-1,3,4-thiadiazolo[3,2-a]pyrimidine with sulfur-containing nucleophiles

Reaction of 2-bromo-7-methyl-5-oxo-5H-1,3,4-thiadiazolo[3,2-a]pyrimidine with sulfur-containing nucleophiles. Kukaniev, M. A.In this study， 139535-33-4 and 142-46-1 are also used.; Shukurov, S. Sh.; Nasyrov, I. M.; Zakharov, K. S. (Inst. Khim., Dushanbe, USSR). Dokl. Akad. Nauk Tadzh. SSR, 33(12), 821-4 (Russian) 1990. CODEN: DANTAL. ISSN: 0002-3469. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The reaction of the title compd. I (R = Br) with R1SH [R1 = cyano, CH2CO2H, substituted Ph, C(NH2):NH, C(NHNH2):NH, C(NHNHCSNH2):NH] gave I (R = R1) in good yields. With some sensitive nucleophiles, the reaction of I (R = SH) with R1X (X = halogen) was performed instead. .
