After heating under reflux for 3.5 hours, the volatiles were evaporated under reduced pressure. The residue was treated with 1.0 M hydrochloric acid (10 ml) and stirred overnight. After filtration, the solid was dissolved in methanol (10 ml) and treated with aqueous sodium carbonate solution (1.0 M, 1 ml). After stirring for 0.5 hours, the volatiles were evaporated under reduced pressure, the solid was stirred with water (10 ml) for 15 minutes, and filtered to provide the title compound (0.020 g, 53% yield) as a white powder. 1H NMR (DMSO-d6) δ 1.37 (t, 3H, J=6.8 Hz, CH3), 2.27 (s, 3H, CH3), 4.12 (q, 2H, J=6.6 Hz, CH2), 6.25 (s, 2H, NH2), 6.75 (s, 1H, Ar), 7.10-7.14 (m, 3H, Ar), 7.40-7.42 (m, 1H, Ar), 7.55 (d, 2H, J=8.0 Hz, Ar), 7.92 (s, 1H, Ar), 9.05 (s, 1H, NH).
