Reaction Steps

A mixture of 4-methyl-2-pyridine carboxaldehyde (1.0 g, 8.26 mmol), sulfolane (10 ml) and benzyl bromide (0.98 ml, 8.3 mmol) was stirred at room temperature for 16 hours, then was heated on a steam bath for 16 hours. Several portions of ethyl acetate were added to the reaction mixture and subsequently decanted to yield a residual gum. The gum was dissolved in water, washed with ether and evaporated to dryness to afford crude formyl-4-methyl pyridinium bromide.
