Versuchsvorschrift

To a solution the product of Step 2 (1.01 g, 1.964 mmol) in methanol (9.8 mL), 4M HCl in Dioxane (1.97 mL, 7.86 mmol) was added. The mixture was stirred at room temperature for 15 minutes. The mixture was diluted with ethyl acetate, washed with saturated NaHCO3, followed by brine, dried (Na2SO4), filtered and concentrated. The residue was purified by column chromatography on silica (40-100% ethyl acetate in hexanes) to afford N-{3-[2-(3-aminooxetan-3-yl)-1,3-thiazol-5-yl]-5-methylphenyl}-4-(trifluoromethyl)pyrimidin-2-amine (386.6 mg, 0.954 mmol, 53.5% yield) as a pale yellow solid. MS ESI: [M+H]+ m/z 408.0. 1H NMR (500 MHz, DMSO-d6) δ 10.26 (s, 1H), 8.83 (d, J=4.8, 1H), 8.07 (s, 1H), 7.97 (s, 1H), 7.47 (s, 1H), 7.28 (d, J=4.9, 1H), 7.17 (s, 1H), 4.87 (d, J=5.6, 2H), 4.58 (d, J=5.7, 2H), 2.32 (s, 3H).
