実験手順

2-Dodecanoylamino-3-hydroxybutanoic acid (15.07 g) and 2-amino-3-hydroxybutanoic acid methyl ester (6.66 g) were condensed with dicyclohexylcarbodiimide (10.31 g). Thereafter, methyl ester was hydrolyzed with sodium hydroxide to give 2-(2-dodecanoylamino-3-hydroxybutanoylamino)-3-hydroxybutanoic acid (10.24 g). The structure thereof was identified by 1H-NMR (400 MHz, CD3OD, r.t.).
