To a mixture of benzyl (2-{[(4-{(3S)-3-[(tert-butoxycarbonyl)amino]piperidin-1-yl}pyridin-3-yl)amino]carbonyl}-7-formylquinolin-3-yl)carbamate (0.200 g, 0.320 mmol) in THF (5.0 mL), methylmagnesium bromide in THF (3.0 M, 0.43 mL, 1.3 mmol) was added slowly at 0° C. under nitrogen. The reaction mixture was stirred at 0° C. for 1 h, then allowed to warm to room temperature. The reaction mixture was then diluted with EtOAc (10 mL), and 1 M HCl was slowly added to adjust the pH to 7. The aqueous layer was extracted twice with EtOAc. The organic extracts were combined, then dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to give the sub-title compound (201 mg, 98%). LCMS calc. for C35H41N6O6 (M+H)+: m/z=641.2. Found: 641.1.
