Procedure

4-[1-(2,5-Difluorobenzyl)-1,2,3,4-tetrahydropyrido[2,3-b]pyrazin-7-yl]benzoic acid (60 mg) was reacted with morpholine as in General Procedure 8 to give the title compound as a light yellow foam (59% yield). M.p. (foam), LCMS: m/z=451.21 (M+H+), 1H-NMR (CDCl3, 400 MHz) δ 3.444-3.48 (m, 2H), 3.62-3.66 (m, 2H), 3.64-3.76 (m, 8H), 4.50 (s, 2H), 5.00 (s, 1H), 6.75 (s, 1H), 6.84-7.15 (m, 3H) 7.43 (dd, J=8.3 Hz, 4H), 7.71 (d, J=1.8 Hz, 1H).
