Procedure

100 mg of 2-[6-fluoro-3-(4-fluorobenzyl)-3,4-dihydroisoquinolin-2(1H)-yl]ethanamine obtained in Example 120-b) and 65 mg of 3-vinyl-5-nitrobenzoic acid were dissolved in 1 mL of chloroform, and 96 mg of WSC was added thereto, followed by stirring for 30 minutes. After completion of the reaction, water was added to the reaction liquid, followed by extraction with ethyl acetate, and the organic layer was then washed with an aqueous sodium bicarbonate solution and saturated brine, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue obtained was purified using silica gel chromatography (chloroform:methanol=10:1) to obtain 112 mg (yield 74%) of a title compound as a yellow solidified product.
