1-(3-bromophenyl)-2-methylpropan-1-one

Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 150 mg of 1-bromo-3-isobutyrylbenzene, 204 mg of ethylene glycol, 350 mg of trimethylorthoformate, and 10 mg of p-toluene sulfonic acid were dissolved in 4 mL of toluene, followed by stirring at 60° C. for 2 days. After completion of the reaction, water was added to the reaction liquid, followed by extraction with ethyl acetate. The organic layer was then washed with saturated brine, dried over anhydrous sodium sulfate and then concentrated under reduced pressure to obtain 146 mg (yield 80%) of a title compound as a pale yellow oily substance. was added to the reaction liquid followed by extraction with ethyl acetate The organic layer was then washed with saturated brine dried over anhydrous sodium sulfate concentrated under reduced pressure
