Versuchsvorschrift
To a solution of 1.9 g of furo[2,3-b]pyridine-5-carboxylic acid ethyl ester (GB 2289276) in 30 ml of THF was added dropwise 17.3 ml of a LiAlH4 (2.3M THF) solution at −20° C. The reaction mixture was stirred for 3 h at −20° C. and then quenched by addition of 1M NaOH solution. The resulting mixture was filtrated over a pad of celite, washed with THF and the filtrate was concentrated in vacuo. Purification by CC using EtOAc yielded 0.5 g of furo[2,3-b]pyridin-5-yl-methanol as yellow oil.
