Participants

Reaction Steps

A solution of 33-2 (0.64 g, 2.5 mmol), 3-1 (0.88 g, 2.5 mmol) and potassium carbonate (2.1 g, 15 mmol) in DMF (14 mL) was heated to 120° C. for 4.5 hours. The reaction was cooled to room temperature, diluted with ethyl acetate, washed with water, brine, dried over sodium sulfate, filtered and concentrated. Purification by silica gel chromatography (1% ethyl acetate/hexane→70% ethyl acetate/hexane) gave the title compound as a foam. MS (M+H+): calculated=471.98, observed=472.1.
