Potassium Acetate → HCID 58125180, compound

Participants

Reaction Steps

To 0.020 g (0.024 mmol) of 10% palladium on carbon was added a solution of 0.14 g (0.24 mmol) of tert-butyl (2R,5R)-2-[(R)-{[tert-butyl(dimethyl)silyl]oxy}(6-chloropyridin-3-yl)methyl]-5-(4-nitrobenzyl)pyrrolidine-1-carboxylate from Step A in 4 mL of anhydrous ethanol followed by 0.024 g (0.24 mmol) of potassium acetate. The resulting suspension was agitated under an atmosphere of hydrogen at 50 psi for 8 h. then filtered through a plug of Celite®. The plug was washed with ethanol (10 mL) and the combined filtrates were concentrated in vacuo. The residue was purified by silica gel chromatography eluting with 40% ethyl acetate in hexanes to afford the title compound as a colorless solid (0.065 g, 54%). LC-MS: m/z (ES) 498.4 (MH)+.
