실험 절차

A mixture containing ethyl 3-methyl-3-methylaminobutanoate (95 g--Preparation 5), benzyl bromide (72 ml), anhydrous potassium carbonate (138 g) and acetonitrile (500 ml) was heated under reflux for 1.5 hours. The mixture was concentrated in vacuo and the residue partitioned between dichloromethane (500 ml) and 10% aqueous potassium carbonate (300 ml). The layers were separated and the aqueous layer extracted with dichloromethane (2 ×100 ml). The combined dichloromethane extracts were dried (MgSO4) and concentrated in vacuo to give an the title compound as a mobile, colourless oil, yield, 150 g.
