Procedure

To a suspension of =(S)-1-([1,2,4]triazolo[4,3-a]pyrazin-8-yl)pyrrolidin-3-amine hydrochloride salt (84 mg, 0.3 mmol), 5-isopropylpyrimidine-2-carboxylic acid (51 mg, 0.3 mmol) in DMF (5 mL) was added diethylisopropyl amine (650 mg, 5 mmol), followed by HATU (120 mg, 0.31 mmol). The resulting solution was stirred at room temperature for 1 h. The reaction mixture was diluted with ethyl acetate and washed with saturated aqueous solutions of KH2PO4 and NaHCO3, followed by brine. The organic layer was concentrated in vacuo and the residue purified by reverse phase HPLC (acetonitrile-H2O with 0.1% TFA as eluent) to give 6 mg of the title compound (5% yield) as a white solid. MS: (ES) m/z found 353.1.
