Reaktionsschritte

To a solution of 4-(formyloxy)-2-methoxyphenyl acetate (16 g, 76 mmol) in THF (50 mL)/H2O (50 mL) was added LiOH (7.7 g, 184.2 mmol). The reaction was stirred at room temperature overnight. The volatiles were removed under reduced pressure. The residue was extracted with EA (50 mL×3). The organic phase was washed with brine (50 mL), dried over Na2SO4, filtrated and concentrated in vacuo to give black oil, which was purified by silica gel column (PE:EA=3:1) to afford 4.8 g of product (40%) as a brown solid.
