Reaction Steps

A solution of (R)-tert-butyl 3-(4-fluoro-2-(1-(3-formylpyrazolo[1,5-a]pyrimidin-5-yl)pyrrolidin-2-yl)phenoxy)propylcarbamate (85.0 mg, 0.176 mmol) in MeOH (2 mL) was first cooled to 0° C., then NaBH4 (4.04 mg, 0.176 mmol) was introduced, and the reaction was stirred at 0° C. for 1 hour. The reaction was diluted with brine and extracted with DCM in a phase separator cartridge. The combined organic extracts were concentrated to provide (R)-tert-butyl 3-(4-fluoro-2-(1-(3-(hydroxymethyl)pyrazolo[1,5-a]pyrimidin-5-yl)pyrrolidin-2-yl)phenoxy)propylcarbamate (86 mg, 101% yield) as beige solid. MS (apci) m/z=468.1 (M+H−H2O).
