Here is a downstream synthesis route of the compound, Application In Synthesis of Methyl 2-bromoimidazo[1,2-a]pyridine-6-carboxylate, blongs to pyridine-derivatives compound. Application In Synthesis of Methyl 2-bromoimidazo[1,2-a]pyridine-6-carboxylate

Example 1 2-({ [2-(2-methylbiphenyl-3-yl)imidazo[l,2-a]pyridin-6-yl]methyl}amino)ethanol Step 1: (2-bromoimidazo[l, To a solution of methyl 2-bromoimidazo[l,2-a]pyridine-6-carboxylate (200 mg, 0.784 mmol) (ArkPharm, catAK-31669) in tetrahydrofuran (5.0 mL) at 0 C was added 1.0 M diisobutylaluminum hydride in tetrahydrofuran (862 mu, 0.862 mmol). The resulting mixture was sitrred at room temperature for 1 h then it was quenched with saturated NH4CI aqueous solution (1 mL), stirred for 1 h then filtered through celite. The organic layer was dried over Na2S04, filtered and concentrated. The residue was used for next step without further purification. LC-MS calculated for C8H8BrN20 (M+H)+: m/z = 227.0; found 227.2.
