Reaction Steps

Methylmagnesium bromide in THF (3.0 M, 5.8 μL, 0.018 mmol) was added to a solution of tert-butyl {(3S)-1-[3-({[5-[(tert-butoxycarbonyl)amino]-2-(2,6-difluorophenyl)-1,3-thiazol-4-yl]carbonyl}amino)-7-oxo-6,7-dihydro-5H-cyclopenta[b]pyridin-4-yl]piperidin-3-yl}carbamate (3.0 mg, 0.0044 mmol) in THF (0.068 mL), which was stirred under N2 and cooled in an ice bath. The reaction mixture was slowly allowed to warmed to room temperature over a period of 1 h. EtOAc was added to the reaction mixture, then 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, dried over Na2SO4, then filtered and concentrated under reduced pressure to give the sub-title compound. LCMS calc. for C34H43F2N6O6S (M+H)+: m/z=701.3. Found: 701.1.
