165 °C

To a stainless steel high pressure reactor was added 5-chloro-2,3-difluoropyridine (18.0 g) and ammonium hydroxide (65 mL). The reaction was heated to 165° C. for three hours. The reaction mixture was then cooled to room temperature and diluted with water (100 mL). The resultant solid was filtered, dried, re-dissolved in CH2Cl2, and passed through a silica gel plug to afford 12.8 g (73%) of the title compound as an off-white solid.
