Sodium carbonate (224 g) and trans-cinnamyl alcohol (200.0 g) were mixed with 2 L of methylene chloride, a slow nitrogen sweep was maintained through the vapor space of the flask and the mixture was cooled to 15-20° C. with a cold water bath. Peracetic acid solution (35%, 381.2 mL) was added over a 3 hour period, maintaining the internal temperature below 25° C. After the peracetic acid addition was complete, the mixture was stirred for 2-3 hours until complete, as shown by HPLC analysis. The mixture was cooled to 10° C. with an ice bath, and a solution of sodium sulfite (160 g) in 1200 ml water was added slowly over 90 minutes, keeping the temperature below 30° C. The phases were separated and the aqueous phase was extracted with methylene chloride (200 mL) to give a solution of the title compound.
