실험 절차

A solution of (S)-(1-methylpyrrolidin-2-yl)methanol (109 mg, 0.94 mmol) in THF (5 mL) was treated with 1 M solution of potassium t-butoxide (0.95 mL, 0.944 mmol) and stirred for 15 min. A solution of Example 9B (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, partitioned between EtOAc and brine, dried (MgSO4), filtered, and concentrated. The residue was purified using an Analogix® Intelliflash280™ (SiO2, 0-15% methanol in dichloromethane) to afford the title compound (175 mg, 75% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 0.91 (t, J=7.3 Hz, 3H), 1.17-1.42 (m, 11H), 1.49-1.83 (m, 5H), 1.82-2.03 (m, 1H), 2.17 (q, J=8.7 Hz, 1H), 2.32 (s, 3H), 2.54-2.67 (m, 1H), 2.83-3.01 (m, 1H), 3.92-4.10 (m, 2H), 4.14 (t, J=7.3 Hz, 2H), 7.28 (d, J=8.8 Hz, 1H), 7.32 (s, 1H), 7.72 (dd, J=9.0, 2.2 Hz, 1H), 7.95 (d, J=2.0 Hz, 1H).
