Reaction Steps

A mixture of 4-chloropyridine hydrochloride (4.50 g), 2-(methylamino)ethanol (2.25 g) and sodium bicarbonate (7.56 g) in isoamyl alcohol (50 ml) was heated under reflux for 70 hours and then evaporated. The residue was extracted several times with hot ethyl acetate and the combined extracts were filtered and evaporated until crystallisation commenced.
