Participants

Reaction Steps

To a mixture of 181 mg of tert-butyl[(1R)-1-(1-naphthyl)ethyl][(3-phenylpiperidin-4-yl)methyl]carbamate, 0.114 mL of triethylamine, and 3.0 mL of THF was added 64 mg of 3,3-dimethylglutaric anhydride at room temperature, followed by stirring at room temperature overnight. To the reaction mixture was added a saturated aqueous sodium hydrogen carbonate solution, followed by stirring, extracting with chloroform, and drying over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 266 mg of 5-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]-3,3-dimethyl-5-oxopentanoic acid as a crude product.
