Reaktionsschritte

2-(Diethylamino)ethyl chloride hydrochloride (624 mg, 3.65 mmol) was added to a stirred solution of p-hydroxybutyrophenone (200 mg, 1.21 mmol) in anhydrous acetone (6 mL) followed by the addition of potassium carbonate (668 mg, 4.84 mmol). The resulting mixture was heated at reflux for 48 hours. The mixture was diluted with ethyl acetate, washed with water (2×) and sat. brine, dried over sodium sulfate, and concentrated to an oil. Flash silica gel column chromatography, eluting with 1:1 hexanes/ethyl acetate, afforded 21 (315 mg, 98%) as a light yellow oil: MS (ES+) m/z 264.1 (M+H)+.
