Reaction Conditions

Reaction Steps

Ethyl N-(6-fluoro-2-methoxyquinoxalin-3-yl)carbamate (27 mg, 0.10 mmol) and 1-phenylpiperazine (24 mg, 0.15 mmol) were dissolved in tetrahydrofuran (2 ml) at room temperature and thereto DBU (23 mg, 0.15 mmol) was added. The resulting mixture was stirred at 70° C. for 7 hours and concentrated under the reduced pressure to remove the solvent, and purified by SiO2 column chromatography. Extraction of the residue with a n-hexane:ethyl acetate (2:1) mixture and concentration gave 34 mg of the titled compound (yield, 88%). 1H NMR (300 MHz, CDCl3): δ 3.29 (s, 4H), 3.77 (s, 3H), 4.14 (s, 4H), 6.89-6.97 (m, 4H), 7.24-7.56 (m, 5H), 7.62-7.71 (m, 1H)
