APPLICATION: DE 83-3303815 4 Feb 1983. PRIORITY: JP 82-15503 4 Feb 1982; JP 82-156687 10 Sep 1982. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The title compds. I [R = H, alkyl, (un)substituted Ph; R1, R2 = alkyl; R1R2 = alkylene], intermediates in the synthesis of vitamin B1 and its analogs, were prepd. by cyclocondensation of RC(:NH)NH2 with (R1O)(R2O)CHC(CN):CHOR3 (II) or (R1O)(R2O)CHCH(CN)CH(OR3)OR4 (R3, R4 = alkyl). Thus, II (R1 = R2 = Me, R3 = Na) was treated with BuOH and concd. H2SO4 to give 90% II (R-R3 = Bu). This was cyclocondensed with MeC(:NH)NH2.HCl to give 85% I (R = Me, R1 = R2 = Bu). .

Process for preparation of thiazolylaminopyrimidinylpiperazines from aminothiazoles, dihalopyrimidines, and piperazines: Process for preparation of thiazolylaminopyrimidinylpiperazines from aminothiazoles, dihalopyrimidines, and piperazines. Larsen, Robert D.; King, Anthony On-ping (USA ). U.S. Pat. Appl. Publ. US 2004023977 A1 5 Feb 2004,14 pp. (English). (United States of America). CODEN: USXXCO. CLASS: ICM: A61K031-506. 1193-21-1 and 60838-50-8 which are cas registry numbers are also used here. ICS: C07D417-14. NCL: 514252180; 514252190; 544295000. APPLICATION: US 2003-618877 14 Jul 2003. PRIORITY: US 2002-PV395819 15 Jul 2002. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Title compds. [I; R = H, alkyl, aminoalkyl, aminocarbonylalkyl; R1 = (substituted) alkyl; R6 = H, halo, cyano, (substituted) Ph, pyridyl], were prepd. by reaction of aminothiazoles (II; R6 as above) with dihalopyrimidines (III; X = halo; R1 as above) to give intermediates (IV; variables as above) and coupling of the thiazolylaminopyrimidines with the corresponding piperazines. Thus, 2-amino-5-cyanothiazole (prepn. given), 4,6-dichloropyrimidine, and K3PO4 were heated 16 h in DMF at 80° to give 53% 2-[(6-chloropyrimidin-4-yl)amino]-1,3-thiazole-5-carbonitrile. This was heated with N-isopropyl-2-piperazin-1-ylacetamide and Et3N in BuOH at 120° for 3 h to give 65% 2-[4-[6-[(5-cyano-1,3-thiazol-2-yl)amino]pyrimidin-4-yl]piperazin-1-yl]-N-i sopropylacetamide. .
