Procedure

The product of Example 9B (240 mg, 0.75 mmol) was treated with fumaric acid (93 mg, 0.8 mmol) in EtOAc/EtOH (v. 1:1, 10 mL) at ambient temperature for 15 h. The title compound was obtained as solid (247 mg, yield, 72%). 1H NMR (300 MHz, CD3OD) δ 1.88–2.22 (m, 3H), 2.31–2.47 (m, 1H), 2.59–2.68 (m, 1H), 3.23–3.50 (m, 5H), 3.89–4.00 (m, 1H), 5.49–5.57 (m, 1H), 6.56 (dd, J=3.0, 1.0 Hz, 1H), 6.69 (s, 2H), 7.29–7.35 (m, 2H), 7.52 (dt, J=8.5, 1.0 Hz, 1H), 7.74 (dd, J=8.5, 1.7 Hz, 1H), 8.12–8.17 (m, 2H) ppm. MS (DCl/NH3): m/z 321 (M+H)+. Anal. Calcd. for C19H20N4O.1.1C4H4O4.0.4H2O: C, 61.73; H, 5.58; N, 12.31. Found: C, 61.67; H, 5.52; N, 12.33.
