Reaction Steps

To a stirred solution of compound 217 (535 mg, 1.65 mmol) in THF (10 mL) is added 3-chloro-propane-1-sulfonyl chloride (0.40 mL, 3.3 mmol) and pyridine (0.27 mL). After 18 h, the mixture is diluted with saturated NaHCO3 and extracted with EtOAc. The organic layer is dried over Na2SO4, filtered, and concentrated. The residue is purified by flash chromatography eluting with a gradient of 0-10% MeOH in DCM to provide 3-chloro-propane-1-sulfonic acid {1-[(S)-4-(2,3-dihydro-benzo[1,4]dioxin-2-yl)-benzyl]-piperidin-4-yl}-amide. LC/MS method 1: ES+ m/z 465.2 [M]+, Rt=0.68 min).
