To a mixture of LiAlH4 (0.08 g, 2.1 mmol) in tetrahydrofuran (25 ml) was added 3-carboethoxy-8-(2-ethyl-6-methylbenzyloxy)-2-methylimidazo[1,2-a]pyridine (1.0 g, 2.8 mmol) in tetrahydrofuran (25 ml). After stirring the mixture at room temperature for 2 h., 0.2 ml of water was added dropwise, followed by 0.2 ml of 15% sodium hydroxide and then 0.6 ml of water. The solids were removed by filtration and the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel using methylene chloride:methanol (9:1) as eluent. Crystallization from diethyl ether gave 0.52 g (60%) of the title compound.
