Nicotinamide → 3-(Isocyanatomethyl)pyridine

Participants

Reaction Steps

To a mixture of nicotinamide (24.4 g., 0.20 mole) and dry ethylene dichloride (2500 ml.) is added oxalyl chloride (38.1 g., 0.30 mole). The mixture is then heated to reflux for 4.5 hours and then cooled to room temperature. It is filtered to give a clear pale orange solution of nicotinyl isocyanate which is used directly in the next step.
