Participants

Reaction Steps

To a solution of ethyl 6-({[(benzyloxy)carbonyl](2-tert-butoxy-2-oxoethyl)amino}methyl)pyridine-2-carboxylate (3.26 g) in tetrahydrofuran (10.0 mL) were added a 1 M aqueous sodium hydroxide solution (8.00 mL), followed by stirring at room temperature overnight. To the reaction mixture was added 1 M hydrochloric acid (8.00 mL), followed by extraction with chloroform. The organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain 6-({[(benzyloxy)carbonyl](2-tert-butoxy-2-oxoethyl)amino}methyl)pyridine-2-carboxylic acid (2.08 g).
