O1C[CH2:4][CH2:3][CH2:2]1.[CH3:6][O:7][C:8]1[CH:13]=[CH:12][CH:11]=[C:10]([NH2:14])[CH:9]=1.C(N(CC)CC)C.C(Br)C=C>C(OCC)(=O)C.O>[CH2:4]([NH:14][C:10]1[CH:11]=[CH:12][CH:13]=[C:8]([O:7][CH3:6])[CH:9]=1)[CH:3]=[CH2:2]To 10 mL of a tetrahydrofuran solution containing 1.0 g of m-anisidine, 1.2 mL of triethylamine and 0.70 mL of allyl bromide were added under cooling with ice. The reaction mixture was stirred for 30 minutes. Water and ethyl acetate were added thereto. The organic layer was separated, and the aqueous layer was separated with ethyl acetate. The organic layer and the extract were combined, the resultant solution was washed with an aqueous saturated sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [eluent; hexane:ethyl acetate=5:1] to obtain 0.36 g of a yellow oily substance, N-allyl-3-methoxyaniline.
