To a −78° C. cooled solution of imidazo[1,2-a]pyridine-7-carboxylic acid methyl ester (1 eq.) in dry THF was slowly added a solution of LiAlH4 in THF (1M in THF, 2 eq.). The reaction mixture was warmed to 0° C. and stirred for 30 min. The reaction mixture was then poured onto a cooled aqueous solution of NaOH 2N, stirred for 5 min and filtered through a pad of celite. The filtrate was partitioned between water and EtOAc, the organic layer was washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure to afford imidazo[1,2-a]pyridin-7-yl-methanol which was used as such without further purification.
