Reaction Steps

To a solution of 1,6-dichloro-9-(1-methyl-1H-pyrazol-4-yl)benzo[c]-1,6-naphthyridine (50 mg, 0.152 mmol) and 2-aminomethylthiazole hydrochloride (92 mg, 0.608 mmol) in DMA (1.5 mL), triethylamine (85 μl, 0.608 mmol) was added. The reaction mixture was heated to 130° C. for 1 h via microwave irradiation. After cooling to room temperature, aqueous sodium hydrogen carbonate (saturated) was added. The aqueous layer was extracted with ethyl acetate. The combined organic extracts were dried over sodium sulfate and concentrated under reduced pressure to afford 1-chloro-9-(1-methyl-1H-pyrazol-4-yl)-N-(1,3-thiazol-2-ylmethyl)benzo[c]-1,6-naphthyridin-6-amine as a yellow solid. LRMS (APCI) calc'd for (C20H16ClN6S) [M+H]+, 407.1; found 407.0.
