Reaction Steps
Bromide 3a (4.95 g, 0.0224 mol) was heated with acetic acid (50 mL) and potassium acetate (2.64 g, 0.0269 mol) at 100° C. for 16 h. Diluted with ethyl acetate and washed with water 3 times. The organic layer was dried (Na2SO4) and concentrated in vacuo to give a crude oil that was subjected to flash chromatography (20% ethyl acetate/80% hexanes) to give 2.48 g (70%) of the desired product 4a. 1H NMR (CDCl3) δ 7.8 (s, 1H), 5.2 (s, 2H), 2.8 (s, 3H), 2.2 (s, 3H).
