Procedure

A solution of 2,6-dibromopyridine (10 g, 42 mmol) and 3-aminopropanol (3.5 mL, 46 mmol) in THF (60 mL) was stirred at reflux for 48 h. The reaction mixture was diluted with EtOAc and washed with H2O and brine, dried (MgSO4) and concentrated in vacuo to give 3-(6-bromo-pyridin-2-ylamino)-propan-1-ol as a light-yellow oil which crystallized on standing at RT to a white solid. MS m/z: 232.0 (M+H). Calc'd for C8H11BrN2O 231.09.
