Reaction Steps

Under a nitrogen atmosphere, to a solution of ethyl 3-cyclopropyl-3-(6-((6-(2-fluoro-5-methoxyphenyl)-5-((tetrahydro-2H-pyran-2-yl)oxy)pyridin-3-yl)methoxy)pyrimidin-4-yl)propanoate (163 mg) in methanol (1.5 mL) was added pyridinium p-toluenesulfonate (7.5 mg), and the mixture was stirred at 50° C. for 20 hr. The reaction mixture was poured into water at room temperature, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (119 mg) as a white amorphous solid.
