A solution of [4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-[4-(tetrahydro-pyran-2-yloxy)-benzyl]-amine (264 mg, 0.666 mmol) in methylene chloride (10 mL) was treated with carbonic acid 4-chlorosulfonyl-phenyl ester ethyl ester (278 mg, 1.05 mmol) and triethylamine (0.3 mL). The reaction mixture was stirred for 60 hr. and water was added. The aqueous solution was washed with methylene chloride (2×). The combined organic layers were dried (sodium sulfate), filtered, and concentrated in vacuo. The crude product was purified via radial chromatography using a solvent gradient (methylene chloride to 5% methanol/methylene chloride) to obtain the title compound of Step A.
