Participants

Reaction Steps

To a mixture of 17.31 g of 4-butoxy-3, 7-diacetoxy-2H-l-benzopyran-2-one (51.79 mmol) in 170 ml of methanol was added 2.66 g of sodium methoxide (49.20 mmol) and the reaction mixture was stirred at room temperature for 3 hours. Then 22.36 g of Amberlyst-15 was added, and the mixture was stirred at room temperature for 1 hour. Amberlyst-15 was filtered off and the filtrate was concentrated under reduced pressure to give a crystalline product. The product was reprecipitated from tertahydrofuran and hexane to give 12.87 g of the title compound. (yield=85%)
