2-phenylpentan-3-one

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

Procedure: A mixture of 2-phenyl-3-pentanone (106 mg, 0.54 mmol) and of tert.-butoxy-bis(dimethylamino)methane (146 mg, 0.75 mmol, 90%) was stirred at 110° C. for 16 h. The reaction was evaporated to dryness, treated twice with toluene and the solvent was evaporated under reduced pressure to give the crude title compound (138 mg, 97%) as a dark brown solid which was used directly in the next step without further purification. The reaction was evaporated to dryness treated twice with toluene the solvent was evaporated under reduced pressure
