Step B To a solution of 3,3,4-trimethyl-pentanoic acid ethyl ester (7 g, 41 mmol) in anhydrous ethyl ether (100 mL) at 0° C. was added a ethyl ether solution (1 M) of LiAlH4 (67 mL, 67 mmol) under nitrogen. The reaction mixture was stirred at 0° C. for 1 h, then poured into a ice-water. The mixture was extracted with ethyl acetate. The organic layer were separated, washed with water, aqueous HCl solution, brine, dried over MgSO4, and concentrated to give 3,3,4-trimethyl-pentan-1-ol as a colorless oil (5.4 g, 100%).
