Reaction Steps
To a solution of 6,6-dimethyl-5,7-dioxaspiro[2,5]-octane-4,8-dione (1.02 g, 6.0 mmol, Aldrich) in 3 mL of DMF was added 4-fluorobenzenamine (666 mg, 6.0 mmol, Aldrich). The reaction mixture was stirred at rt overnight. The reaction mixture was poured into cold water (10 mL). The precipitate that formed was collected by filtration, washed with water, and dried under vacuum to afford the desired product (980 mg, 73%) as a tan solid. MS(ESI+) m/z 224.3 (M+H)+.
