According to Example 2, t-BuMgCl.LiCl (1.01 M in THF 2.18 mL; 2.20 mmol; 1.10 equiv) was reacted with cyclohexanone (178 mg; 2.00 mmol) in the presence of LaCl3.2LiCl (0.33 M; 6.06 mL, 2.00 mmol, 1.00 equiv). Column chromatographical purification (silica; pentane:Et2O, 9:1) afforded the desired product as colorless oil, which started to crystallize after being chilled, mp=49−50° C. (287 mg, 92%).
