Reaction Steps
A solution of 4'-amino-2',3'-ethylenedioxyacetophenone (310 mg, 1.60 mmol) in 2.3 mL of pyridine under nitrogen was cooled in an ice/water bath and 6.9 mL of acetic anhydride was added drop-wise. The mixture was allowed to warm to room temperature and then stirred for 16 hours. The mixture was concentrated by rotary evaporation and the residue was stirred into water. The residue was isolated by filtration and washed with water. Drying gave 2',3'-ethylenedioxy-4'-(methylcarbonylamino)acetophenone (289 mg, 1.23 mmol), m.p. 142°-144° C.
