Reaction Steps

A solution of D1 (1.44 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 (0.71 g). δH (CDCl3) 1.29 (2H, m), 2.05 (2H, m), 2.70 (2H, m), 3.20 (1H, m), 3.30 (2H, m), 6.54 (2H, dd), 6.88 (2H, t).
