Reaction Steps

A solution of 2-amino-6-chloro-N-[4-(4-oxo-1-piperidyl)-3-pyridyl]pyrazolo[1,5-a]pyrimidine-3-carboxamide (50 mg, 0.1296 mmol), azetidine (Hydrochloric Acid (1)) (12.12 mg, 0.1296 mmol) and ammonium formate (8.172 mg, 0.1296 mmol) in toluene was heated at reflux for 1 h with a Dean-Stark apparatus. The reaction was cooled to room temperature and evaporated. The resulting yellow solid was dissolved in DMSO and purified by fractionlynx to yield 2-amino-N-(4-(4-(azetidin-1-yl)piperidin-1-yl)pyridin-3-yl)-6-chloropyrazolo[1,5-a]pyrimidine-3-carboxamide as a white solid. (27 mg, 31%). MS (ES+) 427.2.
