Procedure

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer was charged with DMF (50 mL), 142a (6.0 g, 20.0 mmol), CH3I (4.26 g, 30.0 mmol), and K2CO3 (5.52 g, 40.0 mmol). The mixture was stirred at room temperature for 2 h and diluted with water (200 mL). The resulting white solid was collected by filtration to afford 142b (5.97 g, 95%) as a white solid. MS-ESI: [M+H]+ 314
