To a solution of trans-4-(morpholin-4-yl)cyclohexan-1-ol (213 mg, 1.15 mmol, 2.00 equiv) in distilled N,N-dimethylformamide (10 mL) was added sodium hydride (69 mg, 2.88 mmol, 3.00 equiv, 60% dispersion in mineral oil) at room temperature and the resulting solution was stirred for 0.5 h at 80° C. in an oil bath under nitrogen. Then a solution of 12-chloro-7-thiatricyclo[6.4.0.0^[2,6]]dodeca-1(12),2(6),8,10-tetraene (120 mg, 0.57 mmol, 1.00 equiv) in 3 mL of DMF was added via syringe and the resulting mixture was stirred at 80° C. for 3 hours. After cooling, the reaction was quenched with water and extracted with 5×50 mL of dichloromethane. The combined organic layers were dried over sodium sulfate and concentrated under vacuum. The crude product (100 mg) was purified by preparative HPLC under the following conditions (Waters): Column: Xbridge Prep C18, 5 μm, 19*50 m; water (with 0.05% NH4HCO3) and CH3CN (10% CH3CN up to 40% CH3CN in 10 min); flow rate: 20 mL/min; UV detection at 254 nm. The product-containing fractions were collected and partially evaporated to remove water and CH3CN under reduced pressure. The residue was lyophilized overnight to give the desired 4-(4-[7-thiatricyclo[6.4.0.0^[2,6]]dodeca-1(12),2(6),8,10-tetraen-12-yloxy]cyclohexyl)morpholine (62.7 mg) as a white solid. MS (ES): m/z 359 (M+H)+. 1H NMR (300 MHz, CDCl3): δ 1.51-1.72 (4H, m), 1.82-2.06 (2H, m), 2.22-2.30 (3H, m), 2.42-2.50 (2H, m), 2.68 (4H, m), 2.78-3.06 (4H, m), 3.51-3.96 (4H, m), 4.30-4.48 (1H, m), 6.63 (1H, d, J=5.4 Hz), 8.25 (1H, d, J=5.4 Hz).
