Procedure

NaH (8.38 mg of a 60 wt % dispersion in mineral oil, 0.210 mmol) was added to a stirred, room temperature mixture of tert-butyl (2R,5S)-2-[(R)-{[tert-butyl(dimethyl)silyl]oxy}(phenyl)methyl]-5-(4-{[2-(pyridine-2-yl)ethyl]carbamoyl}benzyl)pyrrolidine-1-carboxylate (120 mg, 0.191 mmol) in tetrahydrofuran (1.9 mL), and the mixture was stirred for 30 minutes. After 30 minutes, iodomethane (0.014 mL, 0.23 mmol) was added and the mixture was stirred for 12 hours. Water was then added and the mixture was partitioned with EtOAc. The aqueous extracts were extracted with EtOAc (3×), and the combined organic layers were washed with brine, dried with Na2SO4, filtered, and concentrated in vacuo to give the product as an orange oil that was used directly in the next step. LC-MS=644.3 (M+1)+.
