実験手順

A mixture of ((S)-1-aminomethyl-butyl)-carbamic acid tert-butyl ester (1.70 g, 8.40 mmol), 3,5-diamino-6-chloro-pyrazine-2-carboxylic acid (1.59 g, 8.43 mmol), N-methylmorpholine (3.8 mL, 34.5 mmol) and HATU (3.2 g, 8.42 mmol) in anhydrous DMF (50 mL) is stirred at RT for 16 h. The reaction mixture is concentrated in vacuo and the resulting residue is purified by column chromatography (basic alumina, MeOH:DCM) to afford the title compound as yellow solid. [M+H]+ 333.
