Reaction Steps
To a solution of 3-(3-bromo-5-chlorophenoxy)-2-chloro-4-methylpyridine (121 mg, 0.363 mmol) in DMSO (1 mL) was added hydrazine hydrate (177 μL, 3.63 mmol) and the mixture was heated at 100° C. for 18 hours. The mixture was then purified on a Luna column (10μ, C18, 250×21.2 cm) eluting with 5-95% ACN/water with 0.1% TFA) to give the title compound. LRMS (M+1)=329.8.
