実験手順

To a solution of 8-(2-chloro-benzenesulfonyl)-2-[4-(3-hydroxy-oxetan-3-yl)-phenyl]-2,8-diaza-spiro[4.5]decan-1-one (described in example 229, 35 mg, 0.07 mmol) in DCM was added DAST (11 uL, 0.08 mmol) at −78° C. The reaction mixture was stirred at −78° C. for 3 hr and then quenched with sat. NaHCO3. The reaction mixture was diluted with DCM and washed with brine, dried (Na2SO4), filtered and concentrated in vacuo to give a crude residue which was purified by flash column chromatography (1:1 AcOEt/heptane) to give 8-(2-chloro-benzenesulfonyl)-2-[4-(3-fluoro-oxetan-3-yl)-phenyl]-2,8-diaza-spiro[4.5]decan-1-one (14 mg, 40%) as a white solid. MS (ESI): 479.1 (MH+).
