Reaction Steps

Potassium tert-butoxide (337 mg, 3 mmol, 3 eq) is added portionwise at room temperature to a solution of cyclobutanol (144 mg, 2 mmol, 2 eq) in DMSO (2 ml) and the mixture is stirred for 2 days. 2-Fluoro-6-(pyrrolidin-3-yl)pyridine hydrochloride (202 mg, 1 mmol, 1 eq) in DMSO (2 ml) is added and the mixture is stirred for 48 hours. Dichloromethane and water are then added to the reaction mixture, and the two phases are separated after vigorous shaking. The aqueous layer is reextracted with dichloromethane. The combined organic layers are dried on MgSO4, filtered and the filtrate condensed under reduced pressure to afford crude 2-(cyclobutyloxy)-6-(pyrrolidin-3-yl)pyridine a1-72, which is used in the next step without any further purification.
