To a mixture of 270 g. (1.62 m.) of p-methoxyphenyl acetate (part A) and 772 ml. of HOAc was added dropwise 77.5 ml. of fuming HNO3 maintaining a temperature of 5° to 10°C. Stirring was continued for 60 minutes at 5° to 10°C following the addition, then the solution was poured into 6 liters of ice. The orange semi-solid was collected by filtration and washed with cold water. The crude product was recrystallized from 1000 ml. of ethanol to give 61 g., m.p. 93°-97°C.
