実験手順

To tert-butyl (2R,5S)-2-[(R)-{[tert-butyl(dimethyl)silyl]oxy}(phenyl)methyl]-5-(4-{[1-(pyridine-2-yl)ethyl]carbamoyl}benzyl)pyrrolidine-1-carboxylate (350 mg, 0.556 mmol) in tetrahydrofuran (1.1 mL), was added sodium hydride (26.7 mg of a 60 wt % dispersion, 0.667 mmol) at 0° C. The reaction was stirred for 30 minutes before methyl iodide (38.2 μl, 0.611 mmol) was added. The resulting red colored reaction was stirred for 3 hours before being quenched by pouring into a separatory funnel containing water and was extracted with ethyl acetate (3×50 mL). The organic extracts were combined and dried with Na2SO4, filtered, and evapourated in vacuo and taken directly to the next step. LC-MS=644.3 (M+1)+.
