Procedure

To the solution of {5-({[tert-butyl(diphenyl)silyl]oxy}methyl)-3-chloro-4-[(2R,6S)-2,6-dimethylmorpholin-4-yl]-2-fluorophenyl}(pyridin-2-yl)methanol (Intermediate 62, 100 mg, 0.165 mmol) in anhydrous DCM (5 mL) was added NMO (37 mg, 0.323 mmol) and TPAP (0.1 eq) at 0° C. and the mixture was 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 product as a solid. Yield: 90 mg, (90%).
