Reaction Steps
To a solution of 1-(3-Amino-4-chloro-phenyl)-propan-2-one (Intermediate D) (0.5 g, 2.73 mmol) in DCM (2 ml) and pyridine (1 ml) is added drop wise methanesulfonyl chloride (0.34 g, 0.23 ml, 3.0 mmol) at 0° C. (ice-bath). The reaction mixture is allowed to warm to room temperature and stirred for 3 days. The solvents are removed in vacuo and the residue is dissolved in EtOAc and washed with water, the organic portion is dried over MgSO4, filtered and concentrated in vacuo. Purification of the crude residue by flash chromatography on silica eluting with EtOAc affords the title compound.
