[4-(5-aminomethyl-2-fluoro-phenyl)-piperidin-1-yl]-[7-fluoro-1-(2-methoxy-ethyl)-4-trifluoromethoxy-1H-indol-3-yl]-methanone (0.250 g, 0.554 mmol) was weighed in a 20 ml glass vial. A solution of L-(+)-tartaric acid at 2.66 mmol/ml in 5:1 (v/v) acetonitrile/water was prepared, and 0.2084 ml of this solution was added to the weighed solid with stirring and heating to ˜60° C. giving a clear solution. The solution was then evaporated in vacuo on a rotary evaporator leaving a glassy solid which was recrystallized in hot isopropyl acetate to which a minimum amount of isopropanol was added to give a clear solution. Upon cooling the crystalline product was isolated by filtration and dried in vacuo at room temperature.
