Reaction Steps

To a stirred solution of 4-methoxybenzylamine (1.2 equiv., 2.4 mmol) and K2CO3 (2.4 equiv., 4.8 mmol) in 5 mL anhydrous 1-methyl-2-pyrrolidinone was added 15 (1 equiv., 2 mmol). The mixture was heated at 130° C. under N2 for 1.5 h, allowed to cool, and the product precipitated by the addition of H2O (5 mL). The mixture was filtered, washed with water, and dried, yielding 16 (1.33 mmol) as a brown solid. 1H NMR (400 MHz, d6-DMSO) δ: 8.75 (1H, t, broad), 8.56 (1H, s), 8.21 (1H, s), 7.43 (2H, d, J=8.6 Hz), 7.04 (2H, d, J=8.6), 4.84 (2H, d, J=5.8), 3.88 (3H, s).
