According to Example 2, MeMgCl (2.9 M; 0.76 mL, 2.2 mmol, 1.10 equiv) was reacted with 1-(2,4,6-trimethyl-phenyl)-ethanone (324 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, crystalline solid, mp=106−107° C. (217 mg, 61%).
