実験手順
A mixture of 151b (500 mg, 2.04 mmol), propan-2-amine (180 mg, 3.06 mmol), and dichloromethane (20 mL) was stirred at room temperature for 2 h. The mixture was concentrated under reduced pressure to afford 151c (400 mg, 74%) as a yellow solid, which was used in the next step without further purification. MS-ESI: [M+H]+ 271.1
