Procedure

To a solution of (R)-5-(2-(5-fluoropyridin-3-yl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (Preparation I, 30.0 mg, 0.092 mmol) and HATU (52.1 mg, 0.137 mmol) in dry DMF (0.5 mL) was added cyclopropylamine (10.5 mg, 0.183 mmol) followed by diisopropylethylamine (35.5 mg, 0.275 mmol). The mixture was stirred under an atmosphere of N2 for 43 hours. The crude mixture was purified by reverse phase chromatography eluting with 0-50% acetonitrile/water to yield the title compound as a white solid (26 mg, 78% yield). MS (apci) m/z=367.0 (M+H).
