Procedure

To a 2-5 mL microwave vessel is charged 5-chloro-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (72 μmol, 40 mg), N,N-diisopropylethylamine (220 μmol, 38 μL), NMP (2 mL), and morpholine (220 μmol, 19 μL). The reaction vessel is flushed with agron and sealed. The reaction mixture was heated to 200° C. in microwave synthesizer for 30 minutes. Upon completion, the NMP was removed in vacuo as an azeotropic using chlorobenzene. The crude product was purified via reverse-phase preparatory HPLC to yield 5-morpholino-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-7-amine as brown-yellow solid. (m+H=347.31, retention time=2.97 min).
