A solution of (1-methyl-1H-imidazol-2-yl)methanol (109 mg, 0.94 mmol) in THF (5 mL) was treated with a 1 M KOtBu/THF (0.95 mL, 0.944 mmol) and stirred for 15 min. A solution of Example 1A (190 mg, 0.47 mmol) was added to the reaction mixture and stirred for 6 hours. The reaction mixture was quenched with saturated NH4Cl solution, concentrated in vacuo and partitioned between EtOAc and brine, dried (MgSO4), filtered, and concentrated. The residue was purified by using an Analogix® Intelliflash280™ (SiO2, 0-60% ethyl acetate in hexanes) to afford the title compound (120 mg, 33% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 1.31 (s, 9 H), 1.50-1.66 (m, 1 H), 1.68-1.96 (m, 3 H), 3.55-3.84 (m, 5 H), 4.05-4.32 (m, 3 H), 5.29 (s, 2 H), 6.86 (s, 1 H), 7.20 (s, 1 H), 7.26 (s, 1 H), 7.52 (d, J=8.8 Hz, 1 H), 7.79 (dd, J=9.0, 2.2 Hz, 1 H), 8.01 (d, J=2.4 Hz, 1 H). MS (DCI/NH3) m/z 523 (M+H)+. Anal. calcd for C25H29F3N4O3S: C, 57.46; H, 5.59; N, 10.72. Found: C, 56.96; H, 5.57; N, 10.46.
