Reaction Steps

4-(3,3-Diethoxyprop-1-yn-1-yl)-6-phenoxypyrimidin-5-amine (2.30 g) was dissolved in 1-methyl-2-pyrrolidone (7.5 mL), and the mixture was cooled to 0° C. A solution (7.6 mL) of potassium tert-butoxide in 1.0 M tetrahydrofuran was added dropwise to this solution, and the mixture was stirred at 0° C. for 30 min. and at room temperature for 1.5 hrs. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was separated and purified by silica gel column chromatography (eluent, hexane:ethyl acetate=90:10→50:50) to give the title compound (1.34 g) as a pale orange solid.
