Reaction Steps

(2R)-2-Amino-3-(2-naphthyl)propionthioamide (0.290 g; 1.2 mmol), (2R)-2-(N-tert-butoxycarbonyl-N-methylamino)-3-(2-naphthyl)propionic acid (0.436 g; 1.3 mmol), HOBT (0.176 g; 1.3 mmol) and EDAC (0.267 g; 1.4 mmol) were dissolved in methylene chloride (20 ml) and stirred 12 hours at RT. Methylene chloride (40 ml) was added and the organic phase was washed with aqueous sodium hydrogensulfate (10%; 40 ml), aqueous sodium hydrogencarbonate (satd.; 40 ml) and dried (Magnesium sulfate). The solvent was removed in vacuo to afford 0,53 g of N-methyl-N-((1R)-2-(2-naphthyl)-1-((1R)-2-(2-naphthyl)-1-thiocarbamoylethylcarbamoyl)ethyl)carbamic acid tert-butylester.
