To a solution of [4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-[4-(tetrahydro-pyran-2-yloxy)-benzyl]-amine (1.70 g, 4.29 mmol) and triethylamine (2.40 mL, 17.2 mmol) in methylene chloride (8–10 mL) at 0° C. was added cyclohexanecarbonyl chloride (1.72 mL, 12.87 mmol) in methylene chloride (30 mL) dropwise. The reaction mixture was stirred for 1 hr. and was quenched with water/saturated sodium bicarbonate (1/1, 40–50 mL). The layers were separated and the aqueous solution was washed with methylene chloride (2×25 mL). The combined organic solutions were dried (magnesium sulfate), filtered, and concentrated. Medium pressure chromatography using a solvent gradient (methylene chloride to 10% methanol/methylene chloride) afforded the title compound of Step A. MS 507 (M+1)+
