A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer was charged with 287e (5.40 g, 1.0 eq., 15.6 mmol), CF3COOH (10 mL), and dichloromethane (50 mL). The mixture was stirred at room temperature for 1 h and concentrated under reduced pressure to afford crude 287f, which was used in the next step without further purification. MS-ESI: [M+H]+ 229.1
