The title compound was prepared in two steps. The first step was accomplished using the procedure for the preparation of compound 2, except that 2-bromobenzylbromide was used in the place of α-Bromo-o-tolunitrile. The crude product was then converted to the title compound by the method used in the preparation of compound 4. 1H-NMR (400 MHz, CDCl3-CD3OD 10:1): δ 7.52 (d, J=8.1 Hz, 1H), 7.24 (t, J=7.8 Hz, 1H), 7.10 (t, J=7.8 Hz, 1H), 6.89 (d, J=7.579 Hz, 1H), 5.27 (s, 1H), 4.92-5.04 (ABq, J=34.1, 15.0 Hz, 2H), 3.27 (bd, J=10.4 Hz, 1H), 3.09-3.18 (m, 1H), 2.89 (m, 1H), 2.70 (t, J=10.9 Hz, 1H), 2.48 (t, J=12.0 Hz, 1H), 2.03 (m, 1H), 1.60-1.71 (m, 1H), 1.42-1.53 (m, 2H). MS (ES) [m+H] calc'd for C16H20BrN4O2, 379.1; found, 379.1.
