Reaction Steps

To a solution of 4-methoxy-2-oxo-1,2-dihydro-pyridine-3-carbonitrile (12.2 g, 81.48 mmol) in acetonitrile (250 ml) were added bromomethyl-cyclopropane (11 g, 81.48 mmol) and potassium carbonate (22.48 g, 162.9 mmol) and the mixture was heated at 110° C. for 24 hours. The mixture was cooled to room temperature and the solid was filtered off The filtrate was evaporated till dryness and the resulting crude residue was then triturated with diethylether to yield pure intermediate 2 (15.72 g, 94%) as a white solid.
