Reaction Steps

A solution of 1-bromo-4-dimethylaminobutan-2-one (13.8 g.) and 2-aminopyridine (4.7 g.) in ethanol (50 ml.) was heated under reflux for 2 hours. Cooling filtration from 1-methylpyrrolidin-3-one methobromide (5.6 g.) followed by concentration and recrystallisation of the residue from methanol gave 2-(2-dimethylaminoethyl)-imidazo [1,2-a] pyridine dihydrobromide, m.p. 262° - 264°.
