Participants

Reaction Steps

Ethyl 2-chloromethylimidazo[1,2-a]pyridine-8-carboxylate (8.4 g, 35.2 m moles) was added to conc. hydrochloric acid 1100 ml), and the mixture was refluxed under heating for 5 hours. The reaction mixture was cooled to room temperature and adjusted to pH 4 with saturated aqueous solution of sodium bicarbonate. The precipitating crystals were collected by filtration to give the object compound (5.67 g, yield 98.4%) as crystal. m.p. 250° C. (decomp.).
