Versuchsvorschrift
To a suspension of 0.56 g (1.1 eq) of LAH in 50 ml of dry THF at 5° C. under nitrogen was added a solution of 2.7 g (13.5 mmol) of methyl 3-(2-methoxy-pyridin-5-yl)-propionate in THF and the reaction mixture was stirred at room temperature for 2 h. The mixture was quenched with 0.6 ml of water, 0.6 ml of 10% NaOH, and 1.8 ml of water successively. The mixture was filtered and the filtrate was concentrated in vacuo to yield 2.0 g (87%) of 2-methoxy-5-(3-hydroxypropyl)-pyridine as a yellow oil.
