Procedure

To a solution of methyl 1-((6-((trans)-4-tert-butylcyclohexyloxy)-5-methylnaphthalen-2-yl)methyl)azetidine-3-carboxylate (80 mg, 0.18 mmol) in EtOH (10 mL) was added aqueous NaOH (2 mL, 20%, 5.0 eq) and 85° C. for 1 h. Then the reaction was cooled to 0° C., the pH of the solution was adjusted to 6 using 1M HCl, concentrated and the residue was dissolved in DCM, washed with water, dried and concentrated to give the title compound as a white solid (40 mg, yield: 52%). ESI-MS (M+H+): 410.3. HPLC: 97.77% 1H NMR (400 MHz, CD3OD) δ: 8.04 (d, 1H), 7.92 (s, 1H), 7.77 (d, 1H), 7.50 (dd, 1H), 7.41 (d, 1H), 4.54 (s, 2H), 4.34-4.26 (m, 5H), 3.74-3.70 (m, 1H), 2.52 (s, 3H), 2.21-2.18 (m, 2H), 1.91-1.88 (m, 2H), 1.49-1.44 (m, 2H), 1.23-1.11 (m, 3H), 0.90 (s, 9H).
