Reaction Conditions

Reaction Steps

Into a 250 mL round bottom flask was added 3-methoxy-propanol (5.26 g, 58.4 mmol) and DMF (156 mL). Sodium hydride (60%, 4.67 g, 3 eq) was added slowly to the solution. After addition the mixture was heated to 90° C. for one hour. 2-chloro-6-amino-pyridine was added and the mixture was heated to reflux for four hours. LCMS showed conversion to product. The reaction was cooled to room temperature and solvent was removed under vacuum. The residue was partitioned between water and ethyl acetate. Organic layer was separated and the aqueous was extracted three times with ethyl acetate (3×50 mL). Organic layer dried over sodium sulfate and filtered; the solvent was removed under vacuum. The residue was dissolved with 2N HCl in MeOH and stirred for five hours at room temperature; the solvent was removed and the residue was purified by column chromatography with 20% ethyl acetate in hexanes yielding 3.12 g (45%) of the title compound as a yellow oil.
