Procedure

Stir a solution of methyl 4-[(4-trifluoromethylphenyl)amino]-7-(3-trifluoromethylpyridin-2-yl)-2-methoxymethyl-[1,8]naphthyridine-3-carboxylate (114 mg, 0.212 mmol), LiOH.H2O (45.0 mg, 1.06 mmol), THF (2 mL) and water (0.1 mL) for 18 hours at room temperature. Add water (20 mL) and acidify with acetic acid. Extract the solution with EtOAc (3×25 mL). Wash the combined organic extracts with brine and dry over Na2SO4. Remove the solvent under reduced pressure to yield the title compound. MS 523.18 (M+1). 1H NMR δ (CDCl3) 11.50 (1H, br s), 8.89 (1H, s), 8.19 (2H, d), 7.88 (1H, dd), 7.67 (2H, m), 7.59 (1H, dd), 7.51 (2H, d), 7.22 (1H, br s), 5.30 (2H, s), 3.65 (3H, s).
