Reaction Steps
A mixture of 2.29 g (10 mmol) 1-(2-methoxy-phenyl)-piperazine hydrochloride, 7.1 mL (100 mmol) 2-bromo-ethanol, 5.52 g (40 mmol) potassium carbonate and 100 mL acetonitrile is stirred at 60° C. overnight. Filtration and concentration in vacuum yields the crude product which is purified via column chromatography over silica gel eluting with dichloromethane/ammonia-saturated methanol 98:2.
