Procedure
According to Example 2, PhMgBr.LiCl (1.00 M in THF; 1.10 mL; 1.10 mmol; 1.10 equiv) was reacted with 1,7,7-trimethylbicyclo[2.2.1]heptan-2-one (152 mg; 1.00 mmol) in the presence of LaCl3.2LiCl (0.33 M; 3.03 mL, 1.00 mmol, 1.00 equiv). Column chromatographical purification (silica; pentane:Et2O, 9:1) afforded the desired product as white solid, mp=41−42° C. (211 mg, 92%).
