Procedure

1-[1-(2-Chloro-3,6-difluorophenyl)ethyl]-7-iodo-1,2,3,4-tetrahydropyrido[2,3-b]pyrazine (53 mg) was coupled to 1-methyl-4-[5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)pyridin-2-yl]piperazine as in General Procedure 4B to give the title compound as an orange solid (15% yield). LCMS: m/z=435.02 (M+H+), 1H-NMR (CDCl3, 400 MHz) δ 1.66 (3H, d, J=7.1 Hz), 2.35 (3H, s), 2.54 (4H, t, J=4.9 Hz), 3.54 (8H, m), 4.89 (1H, bs), 5.31 (1H, m), 6.68 (1H, d, J=8.9 Hz), 6.72 (1H, s), 6.96 (1H, m), 7.05 (1H, m), 7.52 (1H, dd, J=8.8, 2.5 Hz), 7.57 (1H, s), 8.29 (1H, d, J=2.3 Hz).
