Reaction Steps

A mixture of 3-(4,5-dichloropyrimidin-2-yl)pyrazolo[1,5-a]pyrazine (Preparation 32, 75 mg, 0.26 mmol), (5-fluoropyridin-2-yl)methanamine (33 mg, 0.26 mmol) and diisopropylethylamine (52 μL, 30 mmol) in tetrahydrofuran (3 mL) was heated to reflux for 72 h. The solvent was then evaporated under reduced pressure and the crude product was purified by reverse phase chromatography (C-18 silica from Waters©, water/acetonitrile/methanol as eluents [0.1% v/v formic acid buffered] 0% to 100%) to give the title compound (37 mg, 39%).
