Participants

Reaction Steps

10-Amino-2-t-butoxycarbonyl-1,2,3,4-tetrahydro-benzo[b][1,6]-naphthyridine (0.77 g, 2.59 mmol) was added to pyridine (1.0 g, 12.7 mmol). Acetic anhydride (0.53 g, 5.18 mmol) was added to the mixture, followed by refluxing for 7.5 hours. Then, water was added thereto and the resulting mixture was extracted with chloroform. The chloroform layer was dried over anhydrous sodium sulfate and the solvent was distilled off under reduced pressure. The resulting residue was purified by a silica gel column chromatography to obtain the desired compound (0.5 g, 1.47 mmol, 57%).
