Reaction Steps

A solution of N,N-carbonyldiimidazole (800 mg, 5.0 mmol) in 5 mL of dry THF was added dropwise to an ice-cold solution of the product from Step A (1.048 g, 4.0 mmol) and triethylamine (0.60 mL, 4.0 mmol) in 12 mL of dry THF. The resultant mixture was allowed to warm to room temperature overnight, and was then concentrated under reduced pressure. The residue was partitioned between diethyl ether and water, and the ether layer was washed sequentially with 5% aqueous hydrochloric acid, saturated aqueous sodium bicarbonate solution, and saturated aqueous brine, dried (magnesium sulfate), and concentrated under reduced pressure to afford a white powder. Recrystallization from ethyl acetate-hexanes afforded the title compound as a fluffy white solid. LC/MS 289.2 (M+1).
