Participants

Reaction Steps

A mixture of (8) (81% pure, 3.82 g, 10.6 mmol) and (9) in THF (30 mL) was added triphenylphosphine (2.86 g, 10.9 mmol) at room temperature. After the solution was stirred for 15 minutes, potassium hydroxide (0.61 g, 10.9 mmol) in water (6 mL) was added. The resulting mixture was stirred at room temperature overnight. The mixture was acidified to pH˜3 with HCl (2M). The aqueous layer was washed numerous times with diethyl ether, and basified to pH>7 with NaOH (2M). The basic layer was extracted with ethyl acetate. The pooled organic layer was dried over magnesium sulfate. The mixture was filtered. Silica gel was added to the filtrate, and the solvent was removed under vacuum. Purification by chromatography on silica gel (2 to 10% methanol in dichloromethane) gave 1-(2,3-dichlorophenyl)-2-(pyridin-4-yl)ethanamine (10) as a solid (1.71 g, 6.48 mmol, 60% yield).
