Reaction Conditions

Reaction Steps

6-Chloro-2-pyridinamine (1 g, 7.78 mmol) was dissolved in morpholine (6.80 ml, 78 mmol) and heated to 225° C. in a microwave reactor for 60 minutes (˜400 W; 5 mbar). The reaction was cooled to rt and concentrated. The crude product was taken up in DCM (50 mL). After filtration of white solids the crude product was concentrated and purified by silica gel column chromatography eluting with 20-50% EtOAc/hexanes to afford 1 g (5.58 mmol, 72%) of the title compound as a pale yellow solid. LC/MS: (M+H)+: 179.9.
