Reaction Steps

To a solution of 5,6-dichloro-pyridin-3-ol [11860-92-9] (500 mg, 3.05 mmol) and K2CO3 (632 mg, 4.57 mmol) in dry ACN (12 ml) was added fluoro-iodomethane (1.156 ml, 9.15 mmol) at 0° C. The light yellow suspension was stirred for 5 min at 0° C. and then heated up to 120° C. for 30 min. Saturated aq. NH4Cl was added, followed by EtOAc. The organic layer was separated and the aqueous layer was extracted twice with EtOAc. The combined organic layers were washed with brine, dried with Na2SO4, filtered and evaporated to give a brown oil. The crude material was directly used in the next step without further purification.
