Reaction Steps

Tetramethylammonium triacetoxyborohydride (46.7 mg, 0.629 mmol) was added to a DCM (50 mL) solution of (R)-5-(2-(2-(2-aminoethoxy)-5-fluorophenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carbaldehyde (155 mg, 0.420 mmol), and the reaction was stirred at ambient temperature overnight. The reaction mixture was then diluted with brine and extracted with several portions of DCM in a phase separator tube, and the combined organic extracts were concentrated and purified by reverse-phase column chromatography, eluting with 0-90% acetonitrile-H2O, to obtain the title product (32 mg, 21.6% yield). MS (apci) m/z=354.2 (M+H).
