반응 단계

To (E)-N-benzylidene-2-methoxyaniline (5.00 g, 23.7 mmol, 1.00 equiv) in anhydrous THF (106 mL) at 0° C. was added isopropylmagnesium chloride (13.0 mL, 2.0 M in Et2O, 26.0 mmol, 1.10 equiv) and the reaction mixture was stirred at 0° C. for 1 h. A saturated aqueous solution of NH4Cl (50 mL) was added and the aqueous layer was extracted with Et2O (3×50 mL). The combined organic layers were washed with brine (25 mL), dried over MgSO4, filtered, and concentrated. The residue was purified by chromatography on SiO2, eluting with 2% v/v EtOAc/hexanes, to give 2-methoxy-N-(2-methyl-1-phenylpropyl)aniline as a colorless oil (1.72 g, 28% yield).
