Reaction Steps

N-(6-bromo-2-chloro-3-(methylamino)pyridin-4-yl)propionamide 2.78 (213 mg, 0.73 mmol) was dissolved in a mixture of HCl (37% aqueous solution) and AcOH 1:5 (12 mL) and the mixture was heated in a sealed tube at 100° C. After 2 h, LC/MS indicated full conversion to desired product. Reaction mixture was evaporated under reduced pressure. Solids were suspended and stirred for 10 min in a basic aqueous solution of NaHCO3 Solids were collected by filtration to isolate 6-bromo-4-chloro-2-ethyl-3-methyl-3H-imidazo[4,5-c]pyridine 2.79. LCMS found for C9H9BrClN3 as (M+H)+ 273.9.
