実験手順

A solution of the product of Step 1 (50 mg, 0.109 mmol), trimethylsilylacetylene (30.6 μL, 0.218 mmol), DIPEA (57 μL, 0.33 mmol), CuI (4.2 mg, 0.022 mmol) and Pd(PPh3)4 (12.6 mg, 0.011 mmol) in DMF (2.0 mL) was heated to 85° C. overnight. After cooling to room temperature, the mixture was diluted with ethyl acetate (30 mL) and washed with 1:1 water:brine (2×30 mL). The aqueous layers were further extracted with ethyl acetate (30 mL), then the combined organic extracts were dried (Na2SO4), filtered, and concentrated in vacuo. Purification by chromatography on silica gel (100:0 to 50:50, hexanes:ethyl acetate) provided 35 mg (0.073 mmol, 68%) of 2-[5-(3-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}-5-[(trimethylsilyl)ethynyl]phenyl)-1,3-thiazol-2-yl]propan-2-ol as a yellow oil.
