8 mg of 3-benzyl-6-fluoro-1,2,3,4-tetrahydroisoquinoline, 9.3 mg of tert-butyl benzyl(2-oxoethyl)carbamate, 11 mg of sodium triacetoxyborohydride, and 10 μL of acetic acid were dissolved in 0.5 mL of toluene, followed by continuously stirring at room temperature for 30 minutes. 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 (diethyl ether:hexane=1:2) to obtain 14 mg (yield 85%) of a title compound as a yellow oily substance.
