실험 절차
To 4-bromophenylacetone (5.0 g, 23.5 mmol, 1.0 equiv) (Acros Organics 34216) was added N,N-dimethylformamide dimethyl acetal (11.3 ml, 84.6 mmol, 3.6 equiv) and the mixture was heated to 90° C. for 6 hours. The solvents were removed and the resulting gum was dissolved in ethanol (235 ml) with additional heating. Hydrazine hydrate (1.37 ml, 28.2 mmol, 1.2 equiv) was added and the mixture was heated to reflux for 15 hours. The solvents were removed under reduced pressure and the solid was triturated with dichloromethane to afford the title compound, 2.24 g (40%); LCMS (PS-A) Rt 2.87 min [M+H]+ 238. Further material could be isolated from the mother liquor.
