Reaction Steps

3-(3,4-Dichloro-phenyl)-3-(2-hydroxy-ethyl)-pyrrolidine (288 mg, 1.1 mmol) was dissolved in dichloromethane (3 mL) at -78° C. and treated with 4-methylmorpholine (0.25 mL, 2.27 mmol, 2.eq.) and 2,4-dimethoxy-benzoyl chloride (220 mg, 1.1 mmol, 1 eq.) dissolved in 3 mL of dichloromethane. The solution was allowed to warm to 0° C. and stirred for 1 hour. The solution was washed with 1N HCl, and 5% sodium bicarbonate. The organic phase was dried over magnesium sulfate, filtered, and concentrated in vacuo. The residue was chromatographed on silica gel (30 g) with a gradient of 50% ethyl acetate in hexane to 6% methanol in dichloromethane to give 324 mg (69%) of the title compound.
