실험 절차

A solution of 1-(4-chlorophenyl)ethan-1-one (3.0 g, 19.3 mmol) and N,N, dimethylformamide diisopropylacetal (20 ml) was heated at 150° C. for 16 hours. The reaction mixture was cooled to 0° C. and treated with hexanes (20 ml). The resulting solid was collected via filtration and washed with hexanes to provide the title compound: EI-MS (m/z) 209 [M+1]+.
