Procedure

Tf2O (0.224 ml, 1.327 mmol) was added to a stirred solution of pyridine (0.358 ml, 4.42 mmol) and 1′-[(8-cyclopropyl-4-hydroxyquinolin-2-yl)carbonyl]-6-(1-methyl-1H-pyrazol-4-yl)spiro[chroman-2,4′-piperidin]-4-one (450 mg, 0.885 mmol) in CHCl3 (4.5 ml) at −50° C. and the mixture was stirred at room temperature for 3 h. The reaction mixture was diluted with CHCl3 and H2O, the organic layer was washed with brine and dried over MgSO4. After filtration and concentration, the residue was purified by silicagel column chromatography (hexane/EtOAc) to give intended compound as a pale yellow solid.
