Reaction Steps

60 mg of 3-[6-fluoro-3-(4-fluorobenzyl)-3,4-dihydroisoquinolin-2(1H)-yl]propanamine obtained in Example 238-b), 20 mg of 4-aminopyridine, and 34 mg of CDI were dissolved in 1.2 mL of THF, followed by stirring at 60° C. for 3 hours. After completion of the reaction, water was added to the reaction liquid, followed by extraction with chloroform. The organic layer was then washed with 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 10 mg (yield 12%) of a title compound as a yellow oily substance.
