Methyl 2-chloro-3-oxopentanoate → Methyl 8-(cyclohexylmethoxy)-2-ethylimidazo[1,2-a]pyridine-3-carboxylate

Participants

Reaction Steps

A solution of 100 mg (0.485 mmol) of 3-(cyclohexylmethoxy)pyridine-2-amine and 399 mg (2.42 mmol) of methyl 2-chloro-3-oxopentanoate in 4 ml of ethanol was heated at reflux overnight. The mixture was then cooled and concentrated and the residue obtained was purified by preparative HPLC (Method 6). This gave 26 mg (17% of theory) of methyl 8-(cyclohexylmethoxy)-2-ethylimidazo[1,2-a]pyridine-3-carboxylate.
