Reaction Steps

A solution of D1 (1.6 g) in 2M HCl (5 ml) and 1,4-dioxane (20 ml) was heated at 60° C. for 24 h. On cooling, the solution was diluted with water, basified with 2M NaOH solution and extracted with EtOAc (×3). The combined organics were dried (MgSO4) and concentrated in vacuo to give the title compound as a yellow oil (0.719). δH (CDCl3, 250 MHz) 6.88 (2H, t), 6.54 (2H, dd), 3.30 (1H, m), 3.20 (2H, m), 2.70 (2H, m), 2.05 (2H, m), 1.62 (2H, Br), 1.29 (2H, m).
