Reaction Steps
A solution of N-(4-acetyl-5-benzyloxy-2-bromo-phenyl)-acetamide (1.03 g, 2.85 mmol) in anhydrous THF (20 ml) under nitrogen was cooled to −78° C. followed by the dropwise addition of LDA (2.1 ml, 2M solution, 4.3 mmol). The reaction was continued to stir for an hour at −78° C. and then quenched with allyl bromide (0.44 ml, 2.85 mmol). The reaction was allowed to warm to room temperature and continued to stir overnight. The solution was partitioned between EtOAc and water. The organics were collected and washed with water, brine and then dried (MgSO4). Purification by column chromatography in hexane/EtOAc (1:1) afforded a white solid (0.662 g, 58%). LC/MS: RT=2.703 min. 402/404 (MH+).
