Procedure

To the solution of {5-({[tert-butyl(diphenyl)silyl]oxy}methyl)-4-[(2R,6S)-2,6-dimethylmorpholin-4-yl]-2,3-difluorophenyl}(1-methyl-1H-imidazol-5-yl)methanol (Intermediate 69, 50 mg, 0.08 mmol) in anhydrous DCM (5 mL), MnO2 (143 mg, 1.65 mmol) was added at 0° C. and allowed to stir for 1 hour at room temperature. The reaction mixture was filtered and the solvents were removed under vacuum and the residue was purified over silica gel chromatography column using ethyl acetate-pet. ether gradient to give solid. Yield: 37 mg, (75%).
