반응 단계
1-(α-Bromoacetyl)naphthalene (5 g) and 1,1-dimethylurea (6 g) were stirred in anhydrous dimethylformamide (20 ml) at 105° C. overnight. The mixture was cooled, added to ethyl acetate, washed with sodium bicarbonate solution, water, brine, dried with sodium sulphate, filtered and evaporated in vacuo. The title compound was obtained (0.60 g; m.p. 30-32° C.) following silica gel column chromatography of the residue in dichloromethane.
