Versuchsvorschrift

To a flask containing the product of Step 3 (254 mg, 0.67 mmol) was added THF (6.7 mL). The solution was cooled to 0° C. and then methylmagnesium chloride (3.0M in Et2O, 1.1 mL, 3.3 mmol) was added and the reaction was stirred for one hour. After one hour, more methylmagnesium chloride (3.0M in Et2O, 1.1 mL, 3.3 mmol) was added and the reaction was stirred for 30 minutes. The reaction was then diluted with ethyl acetate and carefully quenched with water and then diluted with water. The organic layer was separated, dried over magnesium sulfate, filtered and concentrated. Flash chromatography was used for purification to yield 2-[3-(1,3-thiazol-5-yl)-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl]propan-2-ol (188 mg, 0.49 mmol, 74% yield). MS ESI: [M+H]+ m/z 381. 1H NMR (500 MHz, DMSO-d6) δ 10.26 (s, 1H), 9.07 (s, 1H), 8.82 (d, J=4.8, 1H), 8.20 (s, 1H), 8.03 (s, 1H), 7.79 (s, 1H), 7.45 (s, 1H), 7.28 (d, J=4.9, 1H), 5.12 (s, 1H), 1.46 (s, 6H).
