2-(lH-Indazol-4-yl)-4-mophiholin-4-yl-6-[4-(2,2,2-trifluoro-ethyl’)-piperazin-l- ylmethyl]-thieno[3,2-dlpyrimidine (90).Prepared via 2-Chloro-4-morpholin-4-yl-6-[4-(2,2,2-trifluoro-ethyl)- piperazin-l-ylmethyl]-thieno[3,2-d]pyrimidine, prepared from l-(2,2,2-trifluoro- ethyl)-piperazine.Amine preparation: to BOC-piperazine (4g) in DCM (4OmL) was added trifluoroacetic anhydride (6.06mL) and triethylamine (3.29mL). After stirring overnight the reaction mixture was diluted with diluted with DCM, washed with sodium bicarbonate solution, dried (MgSO4) and the solvent removed in vacuo to yield 4-(2,2,2-trifluoro-acetyl)-piperazine-l-carboxylic acid tert-butyl ester (6.06g).To 4-(2,2,2-trifluoro-acetyl)-piperazine-l-carboxylic acid tert-butyl ester (6.06g) in dry THF (6OmL) was added borane dimethyl sulfide complex (4.5ml) and EPO the reaction mixture was heated to reflux. After 2 h the reaction mixture was cooled to O0C and MeOH was carefully added, followed by water. The organics were extracted into ethyl acetate, dried (MgSO4) and the solvent removed in vacuo to yield 4-(2,2,2-trifluoro-ethyl)-piperazine-l-carboxylic acid tert-butyl ester (4.46g). Treatment with HCl in DCM/MeOH yielded the desired compound, which was isolated as the hydrochloride salt.1H NMR (400MHz, CDCl3): 2.56 (4H, m), 2.69 (4H, m), 2.93 (2H, q), 3.79 (2H, s), 3.85 (4H, m), 4.02 (4H, m), 7.23 (IH, s), 7.44 (IH, d), 7.52 (IH, d), 8.21 (IH, d), 8.94 (IH, s).

692058-21-2 1-Boc-4-(2,2,2-trifluoroethyl)piperazine 16748694, apiperazines compound, is more and more widely used in various fields.
