To a solution of trans-1,4-cyclohexanediol (504.0 mg, 4.34 mmol) in anhydrous DMF (4 mL) was added NaH (139.0 mg, 3.47 mmol, 60% in mineral oil) at 0° C. and then stirred at 0° C. for 1 h. The compound from step 1 (100.0 mg, 0.29 mmol) was added. The mixture was stirred at 0° C. for 0.5 h and then at r.t. 18 hrs. It was then quenched with MeOH (4 mL) and filtered. The filtrate was purified by prep-HPLC to give the title compound (37.0 mg, 30.0%) as an off-white solid. 1H NMR (CDCl3, 40 MHz) δ 8.51 (d, J=7.6 Hz, 1H), 7.94 (dd, J1=8.8 Hz, J2=2.4 Hz, 1H), 7.83 (d, J=2.0 Hz, 1H), 7.56 (t, J=6.8 Hz, 1H), 7.51 (t, J=6.8 Hz, 1H), 7.16 (d, J=7.6 Hz, 1H), 7.11 (d, J=8.8 Hz, 1H), 7.05 (s, 1H), 4.43-4.18 (m, 1H), 3.67 (s, 3H), 3.65-3.62 (m, 1H), 3.16 (q, J=7.6 Hz, 2H), 2.00-1.90 (m, 2H), 1.71-1.65 (m, 2H), 1.42-1.30 (m, 7H).
