実験手順

A sol. of compound E7 (3.55 mmol; 2.84 g) in MeOH (35.5 mL) was treated with para-toluenesulfonic acid (3.91 mmol; 0.74 g), and the mixture was stirred at rt for 30 min. 10% aq. Na2CO3 (20 mL) was added, and the solvents were partially removed under reduced pressure. The resulting suspension was extracted with EtOAc (200 mL), washed with 10% aq. Na2CO3 (100 mL), sat. aq. NaHCO3 (100 mL), and brine (100 mL). The org. extracts were dried over MgSO4, filtered, and the solvents were removed under reduced pressure. The product (2.46 g; 99%) was used for the next step without purification. LC-MS: tR=1.07 min; ES+: 685.50.
