실험 절차

Ethyl 3-(dimethylamino)-2-(5-(6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-2-fluorobenzoyl)acrylate (0.150 g, 0.26 mmol, Intermediate 125) and (S)-2-amino-4-methylpentan-1-ol (0.033 ml, 0.26 mmol) were taken up in THF (2 ml). The mixture was placed in an oil bath and heated to 60° C. for 2 h. Potassium carbonate (0.107 g, 0.78 mmol) was added followed by DMF (1 ml) and the mixture was stirred at 60° C. overnight. Reaction was cooled to room temperature and concentrated in vacuo. The residue was then diluted with water (0.5 mL) and cooled to 0° C. 1N HCl was added drop wise until pH˜4. A light yellow solid was collected by filtration, washed with water, and dried in vacuum oven overnight at 50° C. to give (S)-ethyl 6-(6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-1-(1-hydroxy-4-methylpentan-2-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate (0.072 g, 44%) as a yellow solid.
