Reaction Steps

A suspension of imidazo[1,2-a]pyridine-3-carboxylic acid (5.270 g, 32.5 mmol) in DCM (200 ml) was treated with oxalyl chloride (3.13 ml, 35.8 mmol) followed by the addition of DMF (0.252 ml, 3.25 mmol). The reaction mixture was stirred at RT overnight. The solvent was removed in vacuo to afford the title compound as a hydrochloride salt;
