To a solution of 2,2-dimethoxy-2-(4-pyridyl)-1-(4-fluorophenyl)ethanamine (1.22 g, 4.4 mmol) in THF (10 mL) was added a solution of (3-isocyanatopropyl)-benzene (1.61 g, 10 mmol) in THF (10 mL). The resulting mixture was stirred at room temperature for 30 minutes. The reaction was quenched by addition of water (50 mL) and extracted with ethyl acetate (2×50 mL). The combined ethyl acetate extract was washed with water (50 mL), brine (50 mL) and dried with Na2SO4. After removal of solvent, the crude product was purified by column chromatography to yield the product as a light brown solid.
