The resulting mixture was extracted with DCM (4×50 mL), and the combined organic phases were dried (magnesium sulfate) and evaporated. Chromatography of the residue (5% 2M methanolic ammonia/methanol) gave the title compound as a waxy solid (3.2 g). 1H NMR (400 MHz, CDCl3): 7.19 (d, J=8.6 Hz, 2H), 6.83 (d, J=8.8 Hz, 2H), 3.97 (t, J=6.5 Hz, 2H), 3.4 (s, 2H), 2.48-2.31 (m, 10H), 2.00-1.92 (m, 2H), 1.62-1.52 (m, 8H), 1.47-1.38 (m, 4H).
