Reaktionsschritte

A solution of 1-(4-chlorophenyl)ethane-1-one (35.0 g, 226 mmol) and N,N Dimethylformamide diisopropylacetal (35 mL) was heated to reflux for 16 hours. The reaction mixture was cooled to room temperature and treated with hexanes (50 mL). The resulting solid was collected via filtration and washed with hexanes to provide the title compound as a yellow solid (47.12 g, 99% yield): HPLC Retention Time; 6.45 min (Method B). M+1; 209.
