Reaction Steps

To a solution of Example 18A (100 mg, 0.24 mmol) in a mixture of methanol/acetic acid (1.0 mL/1.0 mL), Zn powder (170 mg, 2.6 mmol) was added at room temperature. The reaction mixture was stirred for 30 minutes, filtered, concentrated under reduced pressure and purified by high pressure liquid chromatography (eluting with 0-70% acetonitrile/water and 0.1% trifluoroacetic acid) to provide the title compound (78 mg, 78%). 1H NMR (400 MHz, methanol-d4) δ ppm 7.62 (br s, 1H), 7.51 (br s, 1H), 7.39 (br s, 1H), 6.30-6.20 (m, 1H), 4.21 (q, 2H), 3.95-3.85 (m, 1H), 3.8-3.5 (m, 4H), 3.15-2.80 (m, 4H), 2.75-2.40 (m, 3H), 2.35-2.20 (m, 2H), 2.10-1.90 (m, 2H), 1.65-1.50 (m, 1H), 1.30 (t, 3H). MS (DCI) m/z 411 (M+H)+.
