Reaction Steps
Aqueous HCl (1.15 mL of a 2M solution) was added to a stirred solution of diethyl [4-(1,4-dioxaspiro[4.5]dec-8-yl)phenyl]malonate (290 mg, 0.77 mmol) in 4 mL THF. The mixture was stirred for 64 h then was partitioned between water and EtOAc. The organic phase was separated and the aqueous further extracted with EtOAc. The organics were combined and dried then concentrated by evaporation to give the title compound (249 mg, 97%) as a gum; 1H NMR δ 1.18 (6H, t), 1.82-1.93 (2H, m), 2.06-2.11 (2H, m), 2.26-2.29 (2H, m), 2.54-2.63 (2H, m), 3.04-3.10 (1H, m), 4.08-4.21 (4H, m), 4.88 (1H, s), 7.31 (4H, s); MS m/e M+Na+ 355.
