Participants

Reaction Steps

The product of Example 39A (200 mg, 0.63 mmol) was treated with fumaric acid (Aldrich, 73 mg, 0.63 mmol) in EtOAc/MeOH (v.10:1, 10 mL) at ambient temperature overnight to give the title compound (247.3 mg, 100%). 1H NMR (MeOH-D4, 300 MHz) 1.76-1.91 (m, 1H), 1.92-2.14 (m, 2H), 2.22-2.37 (m, 1H), 2.51-2.58 (m, 1H), 3.16-3.39 (m, 5H), 3.82 (ddd, J=14.0, 8.2, 1.9 Hz, 1H), 5.40-5.49 (m, 1H), 6.67 (s, 1H), 7.12-7.26 (m, 3H), 7.42-7.49 (m, 1H), 7.89 (s, 1H), 8.05 (d, J=9.5 Hz, 1H), 8.26-8.32 (m, 1H) ppm. MS (DCI/NH3) m/z 321(M+H)+. Anal. Calculated for C19H20N4O.0.5 C4O4H4.0.35 H2O: C, 65.56; H, 5.95; N, 14.56. Found: C, 65.49; H, 6.21; N, 14.34.
