Versuchsvorschrift

A vial was charged with (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 (Example 234, 800 mg, 1.3 mmol) and morpholin-4-yl-acetaldehyde monohydrate hydrochloride (270 mg, 1.47 mmol) in methanol (10 mL). MP-cyanoborohydride (850 mg, 2.0 mmol) beads were added and the resulting mixture was allowed to stir at room temperature overnight. The mixture was filtered and the beads were washed with more methanol. The filtrate was concentrated and purified by Analogix SF15-24 g in DCM/methanol system to give a light yellow solid (380 mg, 45.8%).
