Following the procedure described above in Example 1,4-(4-benzylphenylamino)-6-fluoro-1,7-naphthyridine-3-carbonitrile (0.675 g, 1.90 mmol) was reacted with 4-(2-aminoethyl)morpholine (5.0 mL, 5.0 g, 38 mmol). This process was repeated with three additional aliquots of 4-(4-benzylphenylamino)-6-fluoro-1,7-naphthyridine-3-carbonitrile (0.62 g, 0.62 g, 0.30 g). The contents of all four tubes were worked up together, and the crude product purified by flash chromatography over silica gel (5-6% MeOH in CH2Cl2) to give pure product as bright yellow crystals (1.17 g, 40% yield): 1H NMR (400 MHz, DMSO-D6) δ 2.43 (br s, 4 H) 2.56 (t, J=6.7 Hz, 2 H) 3.31-3.39 (m, 2 H) 3.50-3.66 (m, 4 H) 3.99 (s, 2 H) 6.58 (t, J=4.9 Hz, 1 H) 7.04 (s, 1 H) 7.13-7.35 (m, 9 H) 8.22 (s, 1 H) 8.82 (s, 1 H) 9.56 (s, 1 H); HRMS (ESI+) calcd for C28H29N6O (MH+) 465.2398, found 465.2396.
