Reaction Steps

Step B To a solution of 2-(1-cyclopropyl-1-methyl-ethyl)-malonic acid diethyl ester (4.3 g, 17.8 mmol) in DMSO (30 mL) was added LiCl (1.5 g, 35.6 mmol) and H2O (0.3 mL, 17.8 mmol). The reaction mixture was heated at 170° C. for 4 h, then poured into a ice-water, extracted with ethyl acetate. The organic layer were separated, washed with water, brine, dried over MgSO4, and concentrated to give 3-cyclopropyl-3-methyl-butyric acid ethyl ester as a colorless oil (2 g, 66%).
