Procedure

A vial was charged with 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 (Example 239, 700 mg, 1.14 mmol), morpholin-4-yl-acetaldehyde monohydrate hydrochloride (260 mg, 1.39 mmol) and methanol (10 mL). MP-cyanoborohydride beads (730 mg, 1.71 mmol) were added and the resulting mixture was allowed to stir at room temperature overnight. The reaction went to completion based on LC. The mixture was filtered and the beads were washed with methanol. The filtrate was concentrated under reduced pressure and purified by Analogix SF15-24 g column eluting with dichloromethane/methanol system to give a light yellow solid (310 mg, 37.4%).
