Participants

Reaction Steps

To a solution of 5-{[5-(aminomethyl)-2-methylphenyl]amino}-9-fluorobenzo[c]-2,6-naphthyridin-1(2H)-one (35 mg, 0.10 mmol) in THF (1.0 mL) at 0° C. was added triethylamine (0.03 mL, 0.20 mmol) and trifluoromethanesufonyl chloride (0.01 mL, 0.11 mmol). The reaction was stirred for one hour and then quenched by the addition of citric acid. The mixture was extracted with EtOAc/water and the extracts were washed with brine, dried over MgSO4 and concentrated in vacuo. Purification by silica gel column chromatographpy (0-10% MeOH/CH2Cl2) afforded the title compound. 1H NMR (600 MHz, CD6SO) δ 12.21 (d, 1H), 9.92 (s, 1H), 9.45 (dd, 1H), 8.85 (s, 1H), 7.68 (m, 1H), 7.45 (m, 1H), 7.34-7.38 (m, 2H), 7.26 (d, 1H), 7.22 (d, 1H), 7.09 (d, 1H), 4.32 (s, 2H), 2.12 (s, 3H). LRMS (ESI) calc'd for C21H16F4N4O3 [M+H]+, 481.1; found 481.0.
