Procedure

The product (100 mg, 0.57 mmol) of Example 52F was treated with fumaric acid according to the procedure of Example 40D. The title compound was obtained as white solid (120 mg, 73% yield). 1H NMR (MeOH-d4, 300 MHz) δ 3.18 (dd, J=12.6, 3.4 Hz, 1H), 3.35 (m, 1H), 3.46 (m, 1H), 3.75 (m, 3H), 4.04 (t, J=7.8 Hz, 1H), 4.90 (m, 1H), 6.58 (s, 2H), 7.04 (ddd, J=8.2, 2.7, 1.3 Hz, 1H), 7.27 (dd, J=8.2, 4.8 Hz, 1H), 7.87 (d, 2.7 Hz, 1H), 7.95 (dd, J=4.8, 1.1 Hz, 1H); m/z 176 (M+H)+; Anal. calculated for C11H14ClN3.1.25C4H4O4.0.3H2O: C, 55.31; H, 5.76. Found: C, 54.97; H, 5.47.
