Participants

Reaction Conditions

Reaction Steps

To a slurry of 2-chloro-5-nitropyridine (5 g, 31.5 mmol) and 4,4-difluoropiperidine hydrochloride (4.97 g) in ethanol (40 mL) at ambient temperature was added N,N-diisopropylethylamine (12.00 mL, 69.4 mmol) and the mixture heated to 70° C. for 18 hours. The reaction was concentrated, partitioned between CH2Cl2 and 1M NaOH. The organic phase concentrated and purified by chromatography (elution with 2% MeOH—CH2Cl2 then 3% MeOH—CH2Cl2) to provide the title compound as a yellow oil. MS (DCI) m/z 261 (M+NH4)+.
