Reaction Steps
To an ice-cold solution of ethyl imidazo[1,2-a]pyridine-2-carboxylate (6.1 g, 32 mmol) in dry THF (300 mL) was added lithium aluminium hydride (LAH) (2.4 g, 64 mmol) in portions, and the temperature was maintained at <5° C. for 2 h. THF and water (50 mL, 1:1 v/v) were added slowly and the mixture was filtered. The filtrate was evaporated to dryness. The residue was re-dissolved in EtOAc (60 mL), and washed with brine (10 mL×3). The organic layers were combined, and the solvent was removed to give the title compound (4.3 g, yield 90%). ESI MS: m/z 149 [M+H]+.
