To a solution of 2-((6-((trans)-4-tert-butylcyclohexyloxy)naphthalen-2-yl)methylamino)acetonitrile (240 mg, 0.69 mmol) in water and isopropanol (10 mL, 1:5) was added NaN3 (50 mg, 0.76 mmol, 1.1 eq) and ZnBr2 (153 mg, 0.69 mmol, 1.0 eq), then refluxed for 18 h. The reaction was cooled to 0° C. and saturated NaHCO3 was added. The mixture was extracted with DCM (20 mL×3) and the aqueous layer was destroyed by NaClO solution. The organic layer was concentrated and the residue was the title compound as a white solid (27 mg, yield: 11%). ESI-MS (M+H+): 394.3. HPLC: 91.15%, 1H NMR (400 MHz, CD3OD) δ: 7.82 (s, 1H), 7.79-7.72 (m, 2H), 7.42 (d, 1H), 7.16 (d, 2H), 4.47-4.31 (m, 5H), 2.26 (d, 2H), 1.89 (d, 2H), 1.45-1.41 (m, 2H), 1.24-1.09 (m, 3H), 0.88 (s, 9H)
