HCID 684507096-(2-aminoethyl)pyridin-2(1H)-one hydrobromide

Conditions

Temperature: 80 °C

Procedure

To 700 mg of 2-(6-methoxypyridin-2-yl)ethylamine was added 10 ml of a 47% aqueous hydrogen bromide solution, followed by stirring at 80° C. for 60 hours. After evaporating the solvent, the residue was washed with diethyl ether to obtain 1.21 g of a 6-(2-aminoethyl)pyridin-2(1H)-one hydrobromide as a pale brown solid.
