実験手順

(S)-ethyl 6-(6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-1-((1-(2-morpholinoethyl)pyrrolidin-3-yl)methyl)-4-oxo-1,4-dihydroquinoline-3-carboxylate (Example 236, 380 mg) was dissolved in methanol (3 mL) and tetrahydrofuran (3 mL). To this solution was added 24 wt % sodium hydroxide (1 mL) and the reaction was stirred at room temperature overnight. The solution was then concentrated to remove the organic solvents. Water (10 mL) was added and the aqueous layer was carefully acidified to pH 6˜7 with 1N hydrochloric acid. The solution was centrifuged to help isolate the solid that precipitated which was washed with cold water once to give a light yellow solid (300 mg, 82.1%) after drying.
