475272-54-9, (S)-1-Boc-3-Isopropylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Intermediate 8 7-[(2S)-2-Isopropylpiperazin-1-yl]thiazolo[5,4-d]pyrimidin-5-amine hydrochloride [0228] Intermediate 4 (2.2 mmol) and tert-butyl (3S)-3-isopropylpiperazine-1-carboxylate (0.5 g, 2.2 mmol) in DMF (10 mL) and DIPEA (0.34 g, 2.63 mmol) were heated at 110 C. for 6 h. The reaction mixture was allowed to cool, then stirred overnight at room temperature. The reaction mixture was concentrated in vacuo, then partitioned between EtOAc and water. The organic layers were dried over sodium sulfate and concentrated in vacuo, then the crude material was purified by column chromatography (silica gel: 100-200 mesh, isohexanes:EtOAc, gradient 50% to 100% EtOAc) to give an off-white foam. This was taken up in 4N HCl in 1,4-dioxane (5 mL) and methanol (1 mL), and stirred for 1 h. The reaction mixture was concentrated in vacuo and triturated with diethyl ether to give the title compound (0.08 g, 12%). LCMS (ES+) 279 (M+H)+, RT 0.91 minutes (method 3)., 475272-54-9
As the paragraph descriping shows that 475272-54-9 is playing an increasingly important role.
