Reaction Steps

The product of Example 1B (113 mg, 0.36 mmol) was treated with fumaric acid (46 mg, 0.4 mmol) in EtOAc/EtOH (v. 1:1, 4 mL) at ambient temperature for 10 h. The title compound was obtained as solid (131 mg, yield, 89%). 1H NMR (300 MHz, CD3OD) δ 1.73–2.13 (m, 3H), 2.23–2.37 (m, 1H), 2.43–2.51 (m, 1H), 3.12–3.43 (m, 5H), 3.64–3.76 (m, 1H), 4.77–4.88 (m, 1H), 6.67 (s, 1.4H), 6.99–7.18 (m, 4H), 7.38 (s, 1H), 7.39–7.43 (m, 1H), 7.61 (dt, J=8.8, 2.0 Hz, 2H), 7.80 (d, J=7.8 Hz, 1H) ppm. MS (DCl/NH3): m/z 319 (M+H)+. Anal. Calculated for C21H22N2O.0.85C4H4O4: C, 70.27; H, 6.14; N, 6.72. Found: C, 70.20; H, 6.35; N, 6.88.
