Procedure

A mixture of 1-chloroimine isoquinoline II (500 mg, 1.6 mmol), 4-methoxy benzylamine (877 mg, 6.4 mmol), and potassium carbonate (2 g, 15 mmol) in DMF was refluxed overnight. The reaction mixture was cooled to room temperature, diluted with water, and extracted with ethyl acetate. The combined organic extracts were washed with water, dried, and concentrated. The residue was purified by column chromatography on silica gel with n-hexane-ethyl acetate (3:1) to afford compound III (310 mg, 47%). 1H NMR (300 MHz, CDCl3) δ: 7.74-7.62 (m, 3H), 7.45-7.33 (m, 4H), 7.22 (m, 1H), 6.92 (m, 3H), 6.66 (m, 1H), 5.24 (s, 1H), 4.91 (d, 2H), 3.91 (s, 3H), 3.85 (s, 3H), 3.09 (s, 6H).
