Versuchsvorschrift
A solution of 2-(2-methoxypyridin-4-yl)ethanamine hydrochloride (0.8 g, 4.23 mmol) was dissolved in 45% HBr (7 mL) and HOAc (7 mL). The mixture was heated to reflux for 4 hours and then the solvent was removed under reduce pressure. The residue was washed with THF (20 mL) and dried to give 4-(2-aminoethyl)pyridin-2(1H)-one hydrobromide (0.8 g 86%) as a grey solid. LC-MS: 139 [M+H]+, tR=0.28 min.
