Reaction Steps

A solution of (R)-2-(1H-indol-3-yl)-1-(5-methyloxazol-2-yl)ethylamine (240 mg, 1.0 mmol) and 4-dimethylamino-4-phenylcyclohexanone (218 mg, 1.0 mmol) in 1,2-dichloroethane (15 mL) was mixed with powdered sodium triacetoxyboron hydride (317 mg, 1.5 mmol) and acetic acid (120 mg, 2.0 mmol) and stirred for 18 h at room temperature. The mixture was then diluted with ethyl acetate (80 mL), washed with sodium hydrogencarbonate solution (20 mL) and dried with sodium sulphate. The solvent was removed in a vacuum and the residue purified by flash chromatography (15 g, 12×2.5 cm) with methanol/dichloromethane (1:4).
