Phenylpyruvic acid → HCID 54264201, compound

Participants

Reaction Steps

L-Alanyl-N-(indan-2-yl)glycine (1.0 g) and 6.0 g of phenylpyruvic acid are dissolved in 50 ml of 70% aqueous potassium hydroxide. Sodium cyanoborohydride (1.0 g) is added to this solution. After allowing the mixture to stand at room temperature overnight, the solvent is distilled off under reduced pressure, the residue is dissolved in 2 ml of water, made absorbed on a Dowex 50 (H+) [trade name of ion-exchange resin] column and eluted with 2% pyridine. The solvent is distilled off under reduced pressure, the residue is purified by silica gel column chromatography using acetonitrile-methanol (4:1) as the developer to give 0.3 g of N-(1-carboxy-2-phenylethyl)-L-alanyl-N-(indan-2-yl)glycine as colorless powder.
