実験手順

(R)-ethyl 6-(6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-4-oxo-1-(piperidin-3-yl)-1,4-dihydroquinoline-3-carboxylate (Example 262, 0.150 g, 0.24 mmol) was taken up in isopropanol (2 mL) and methyl vinyl sulfone (0.026 mL, 0.29 mmol) was added. The reaction mixture was stirred at 100° C. for 18 h in a sealed vessel, then cooled to room temperature and the solvent was removed in vacuo and loaded directly onto silica. Purified by flash column chromatography on silica gel using (dichloromethane-methanol) gave (R)-ethyl 6-(6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-1-(1-(2-(methylsulfonyl)ethyl)piperidin-3-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate (0.110 g, 62.5%).
