Reaction Steps
1.33 ml of a 1.6-molar solution of n-butyllithium (2.13 mmol) in pentane were added dropwise at room temperature under argon for 2 minutes to a stirred solution of 500 mg (2.13 mmol) 3-benzyl-2,2,4,4-tetramethyl-3-pentanol in 4 ml THF. The solution obtained was stirred for 30 minutes, then 275 μl (2.13 mmol) benzaldehyde, 290 mg (2.13 mmol) ZnCl2 and 2 ml HMPA were added. The reaction mixture was heated to 70° C. and stirred for 4 hours at this temperature. Subsequently, it was cooled to room temperature and processed analogous to Example 1. The raw product obtained was cleaned by means of a silica column with 35% diethyl ether/light gasoline. There was obtained the alcohol as a colorless oil.
