Reaction Conditions

Reaction Steps

Maleimide (0.60 g, 6.05 mmol) and triphenylphosphine (1.57 g, 5.97 mmol) were dissolved in 40 mL of acetone and the reaction mixture was stirred at 65° C. for 1 h. After cooling down to room temperature, the solid was collected by filtration, washed with acetone, and dried to afford compound 11 in 82.5% (1.77 g) yield as a white solid.
