Versuchsvorschrift

To a solution of 3,5-diamino-6-chloro-pyrazine-2-carboxylic acid (0.225 g, 1.2 mmol) and HATU (0.46 g, 1.2 mmol) in DMF (10 mL) is added N-methylmorpholine (0.53 mL, 4.8 mmol) and ((S)-1-aminomethyl-2-phenyl-ethyl)-carbamic acid tert-butyl ester (0.3 g, 1.2 mmol) and the resulting yellow solution is stirred at RT for 18 h. The solvent is removed in vacuo and the residue is diluted with water (10 mL). The precipitate which forms is collected by filtration and dissolved in DCM (5 mL). TFA (1 mL) is added and the solution stirred at RT for 1 h. The solvent is removed in vacuo, and the residue is purified by reverse phase chromatography (Isolute™ C18, 0-100% acetonitrile in water with 0.1% TFA) to yield the title compound. [M+H]+ 321
