Versuchsvorschrift

At 0° C., KOtBu (1.81 g, 16.2 mmol) is carefully added to methanol (25 mL). Hydroxylamine hydrochloride (963 mg, 13.9 mmol) is then added to this solution. The suspension is stirred for 30 min before 2-ethyl-6-methyl-isonicotinonitrile (675 mg, 4.62 mmol) is added. The mixture is refluxed for 1 h, the solvent is evaporated. The residue is dissolved in water, extracted three times with EA. The org. extracts are dried over MgSO4, filtered, evaporated and dried under HV to give 2-ethyl-N-hydroxy-6-methyl-isonicotinamidine (897 mg) as a white powder, LC-MS: tR=0.31 min, [M+1]+=180.32.
