Reaction Steps

A suspension of 5-chloro-1,8-naphthyridin-2(1H)-one (0.050 g, 0.00028 mol), 7-hydroxy-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid (0.080 g, 0.00042 mol), and cesium carbonate (0.270 g, 0.000829 mol) in DMF (1 mL) was subjected to microwave heating (180° C.) for 15 min. The reaction mixture was dissolved in water and then acidified to pH of 2 with 1N HCl. The mixture was extracted with EtOAc (4×). The combined organic solutions were dried over MgSO4, filtered, and concentrated. The residue was triturated with DCM and hexanes to produce 7-[(7-oxo-7,8-dihydro-1,8-naphthyridin-4-yl)oxy]-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid as a white solid (0.066 g, 71%). LCMS: (FA) ES+ 337.3.
