Reaction Conditions

Reaction Steps

A mixture of 2-chloro-6-(methyloxy)-3-nitropyridine (10 g, 53 mmol), aminoacetaldehyde dimethylacetal (5.6 g, 6.2 ml, 53 mmol) and potassium carbonate (7.4 g, 53 mmol) in acetonitrile (100 mL) and DMF (10 mL) was heated at 40° C. for 30 minutes. The mixture was filtered and extracted with DCM and brine. The organic extract was added to a silica column which was then eluted with 0-100% ethyl acetate in hexane affording a yellow solid (12.4 g, 90%).
