Reaction Steps

To a stirred solution of ethyl 2,3-dimethyl-8-(2,6-dimethylbenzylamino)-imidazo[1,2-a]pyridine-6-carboxylate (1.2 g, 3.4 mmol) in tetrahydrofuran (30 ml) was added LiALH4 (0.7 g, 18.5 mmol) during 20 min. at 5° C. 0.7 ml of water was added dropwise, followed by 0.7 ml of 15% sodium hydroxide and then 2.1 ml of water. The solids were removed by filtration and washed thoroughly with methylene chloride:methanol (1:1). The filtrate and washings were combined and the solvents were removed under reduced pressure. The residue was purified by column chromatography on silica gel using methylene chloride:methanol (10:1) as eluent. Treating the residue with diethyl ether and filtration gave 0.7 g (67%) of the title compound.
