Reaction Steps

Ethyl 6-(6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-1-(cis-2-hydroxycyclohexyl)-4-oxo-1,4-dihydroquinoline-3-carboxylate (Example 253, 0.240 g, 0.38 mmol) was suspended in MeOH (6 mL) in a microwave vessel (CEM). THF (3.00 mL) was added. A 2.0 M aq solution of LiOH (0.381 mL, 0.76 mmol) was added. The microwave vessel was heated in the microwave at 100° C. for 15 min After cooling to room temperature, the solvent was removed in vacuo to give a residue which was purified by flash column chromatography on silica gel using (dichloromethane-methanol) to give 6-(6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-1-(cis-2-hydroxycyclohexyl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (0.113 g, 49%).
