Procedure

A vial was charged with (S)-ethyl 6-iodo-4-oxo-1-(pyrrolidin-3-ylmethyl)-1,4-dihydroquinoline-3-carboxylate hydrochloride (Intermediate 98, 1.0 g, 2.16 mmol), 6-(3-ethylureido)-4-(4-trifluoromethylthiazol-2-yl)pyridin-3-ylboronic acid (Intermediate 17, 940 mg, 2.61 mmol), and sodium bicarbonate (730 mg, 8.65 mmol) in dimethoxyethane (10 mL) and water (2 mL). The reaction mixture was purged by N2 for about 5 min, then trans-dichlorobis(triphenylphosphine)palladium (II) (160 mg, 0.228 mmol) was added. The reaction was heated for 1 hour at 80-85° C., then cooled to room temperature, and water (10 mL) was added. The precipitate that formed was collected by filtration to give (S)-ethyl 6-(6-(3-ethylureido)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-3-yl)-4-oxo-1-(pyrrolidin-3-ylmethyl)-1,4-dihydroquinoline-3-carboxylate (1.16 g, 87.2%) as a light brown solid after drying under vacuum at 40° C. overnight.
