Reaction Steps

N-[3-(7-Chloro-1-methyl-2-oxo-1,2-dihydro-[1,6]naphthyridin-3-yl)-4-methyl-phenyl]-3-trifluoromethyl-benzamide (50 mg, 0.106 mmol) is mixed with 3-(aminomethyl)-pyridine (18 mg, 0.16 mmol), Pd2(dba)2 (2.4 mg, 2.5%), 1,3-Bis(2,6-di-i-propylphenyl)-imidazolium chloride (2.3 mg, 5%) and potassium tert-butanoxide (17.8 mg, 0.159 mmol) under an argon environment. 6 mL of anhydrous 1,4-dioxane is added and the reaction is continued at 100° C. for 14 hours. After cooling and removal of solvent under vacuum, the crude product is dissolved in DMSO and purified by reverse phase preparative HPLC to give the final product as a pale solid: 1H NMR 400 MHz (DMSO-d6) δ 10.46 (s, 1H), 8.79 (s, 1H), 8.68 (d, 1H, J=4.6 Hz), 8.44 (s, 1H), 8.29 (s, 1H), 8.24 (t, 2H, J=7.5 Hz), 7.96 (d, 2H, J=7.8 Hz), 7.76 (m, 3H), 7.65 (m, 2H), 7.24 (d, 1H, J=8.3 Hz), 6.46 (s, 1H), 4.74 (s, 2H), 3.52 (s, 3H), 2.11 (s, 3H); MS m/z 544.3 (M+1).
