Lithium Hydroxide → 1-(2-(Dimethylamino)ethyl)-4-oxo-6-(6-(3-propylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-1,4-dihydroquinoline-3-carboxylic acid

Participants

Reaction Steps

To a solution of ethyl 1-(2-(dimethylamino)ethyl)-4-oxo-6-(6-(3-propylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-1,4-dihydroquinoline-3-carboxylate (Example 150, 100 mg, 0.16 mmol) in tetrahydrofuran (2 mL) was added lithium hydroxide (1 M, 650 μL) and the mixture was stirred for 1 h at room temperature. The organics were removed under a stream of nitrogen and the precipitate that formed was isolated by filtration, washed with water (1 mL), and dried in a vacuum oven overnight at 40° C. to give 70 mg of yellowish solid.
