反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a 1:1 mixture of ether (1.85 mL) and 30% ammonium hydroxide (1.85 mL) was added drop-wise 2,2-bis(trifluoromethyl)oxirane (1.00 g, 5.5 mmol). The reaction mixture was stirred for 2 h at rt, then diluted with ether and H2O. The aqueous layer was extracted twice with ether and the combined ether layer was dried over MgSO4, filtered and concentrated to give 2-(aminomethyl)-1,1,1,3,3,3-hexafluoropropan-2-ol as a semi solid (0.87 g, 81% yield). 1H NMR (400 MHz, CDCl3) ppm 3.14 (s, 2H), 3.25 (s, 1H). The aqueous layer was extracted twice with ether the combined ether layer was dried over MgSO4 filtered concentrated

实验步骤: To a stirred solution of 2-fluoro-9-isopropyl-6-[(pyridine-3-ylmethyl)-amino]purine (50 mg, 0,175 mmol) in n-BuOH/DMSO (2.5 ml, 4:1) at room temperature and under an argon atmosphere was added diisopropylethylamine (135 mg, 1.05 mmol) followed by 2-(aminomethyl)-1,1,1,3,3,3-hexafluoropropane-2-ol (prepared from the reaction of 30% ammonium hydroxide with 2,2-bis[trifluoromethyl]oxirane). The reaction mixture was placed in a preheated oil bath at 140° C. and stirred at this temperature for 3 days. The reaction was followed by LCMS and was gone by only 30%. Additional newly prepared 2-(aminomethyl)-1,1,1,3,3,3-hexafluoropropane-2-ol was added and the reaction continued. This addition was done on three more consecutive days to achieve complete conversion. After removal of solvent, the residue was purified by silica gel flash column chromatography to give the title compound as a pale brown powder (19 mg, 23%); δH (CDCl3, 500 MHz) 1.57 (6 H, d, J 7.5, CH[CH3]2), 3.48-3.44 (1 H, m, NHCHHCOH[CF3]2, 3.86-3.81 (1 H, m, NHCHHCOH[CF3]2, 4.62-4.555 (1 H, m, CHMe2), 4.78-4.74 (2 H, m, NHCH2ArH), 5.35 (1H, s, br, OH), 6.36 (1 H, s, br, NH), 7.27-7.22 (2 H, m, ArH), 7.7-7.67 (1 H, m, ArH), 8.5 (1 H, d, J 5, ArH), 8.66 (1 H, s, ArH); δC (CDCl3, 500 MHz) 159.99 (C), 154.63 (C), 149.53 (C), 149.05 (C), 148.6 (CH), 137.79 (C), 135.41 (C), 135.38 (CH), 135 (CH), 123.44 (CH), 75.03 (C), 47.62 (CH2), 46.84 (CH), 42.05 (CH2), 22.1 (2×CH3); m/z 464.2 (M+H) The reaction mixture was placed in a preheated oil bath at 140° C.
