Conditions

Temperature: 80 °C

Procedure

A mixture of 7-benzyl-4-hydroxy-8-oxo-7,8-dihydro-[2,7]naphthyridine-3-carboxylic acid methyl ester (35 mg, 0.11 mmol) and cyclopropylamine (0.080 mL, 1.1 mmol) in 2 mL of EtOH was heated in a sealed tube at 80° C. for 4 h. After cooling to r.t., acetic acid (0.1 mL) and water (3 mL) were added. The resulting suspension was filtered and the solid isolated was dried under high vacuum to afford 17 mg of the title compound. MS: (+) m/z 336.00 (M+1).
