Reaction Steps

Potassium phthalimide (1.67 g, 9.00 mmol) was added to a solution of the product from step b (2.10 g, 4.50 mmol) in dry N,N-dimethylformamide (10 ml), under an atmosphere of argon. The mixture was stirred and heated at 100° C. for 18 h and allowed to cool to room temperature. Water (75 ml) was added and the mixture extracted with dichloromethane (3×40 ml). The combined extracts were evaporated, the residue dissolved in ethyl acetate (75 ml) and the solution washed five times with brine. The solvent was evaporated and the residue purified by flash column chromatography (silica; ethyl acetate), from which the product was isolated as a yellow oil (1.75 g, 93%).
