Reaction Steps

Ethyl 8-(2,6-dimethylbenzylamino)-3-methylimidazo[1,2-a]pyridine-2-carboxylate (5.2 g, 0.015 mol) was solved in tetrahydrofuran (100 ml) and LiAlH4 (1.15 g 0.03 mol) was added. After stirring the mixture at room temperature, for 45 min, 1.15 ml of water was added dropwise, followed by 1.15 ml of 15% sodium hydroxide and then 3.45 ml of water. The solids were removed by filtration and washed thoroughly with methylene chloride. The filtrate and washings were combined and dried and the solvents were removed under reduced pressure. Purification of the residue by column chromatography on silica gel using methylene chloride methanol (10:2) as eluent gave 3.2 g (73%) of the title compound.
