Reaction Steps
5-(1-Benzyl-2-oxo-1,2,3,4-tetrahydropyrido[2,3-b]pyrazin-7-yl)pyridine-2-carbonitrile (32 mg) was mixed with ethanol (1.5 mL) and 4 N HCl (2.0 mL) in dioxane and then heated in a microwave oven at 150° C. for 80 minutes. The reaction mixture was concentrated and purified with preparative reversed-phase HPLC to give the title compound as an orange solid. LCMS: m/z=389.22 (M+H+), 1H-NMR (CD3OD, 400 MHz) δ 1.42 (3H, t, J=7.1 Hz), 4.44 (4H, m), 5.35 (2H, s), 7.28 (1H, m), 7.37 (5H, m), 7.55 (1H, d, J=1.8 Hz), 8.00 (1H, d, J=1.8 Hz), 8.03 (1H, dd, J=8.1, 2.3 Hz), 8.17 (1H, d, J=8.3 Hz), 8.69 (1H, d, J=2.0 Hz).
