Reaction Steps

4-Chloro-pyridine-3-carbaldehyde (10.0 g, 71 mmol) was dissolved in EtOH (12 ml). H2O (30 ml), ice (30 g) and hydroxylamine hydrochloride (5.40 g, 78 mmol) were added. To the resulting mixture was added over a period of 2 min a solution of 2 N NaOH (88.3 ml, 177 mmol). The resulting yellowish solution was stirred 2.5 h at r.t. before neutralisation with AcOH (pH=6). White crystals precipitated, were collected by filtration and washed with H2O (30 ml). The product was dried 1 h at 50° C. on the high vacuum to yield 9.25 g (84%) of a off white solid. m/z=157.1 ([M−H]−).
