Reaktionsschritte
To a solution of methyl 3-amino-6-bromopicolinate (2.31 g, 10 mmoles) in 2:1 THF/MeOH (51 mL) was added 1.0 M LiOH (17 mL, 17 mmoles). After stirring for 16 hours, 1 N HCl (17 mL, 17 mmoles) was added and the THF/MeOH was removed in vacuo. The resulting solid was filtered, rinsed with cold H2O (4×20 mL) and pumped on yielding 3-amino-6-bromopicolinic acid (97%). LCMS (m/z): 216.9 (MH+); LC Rt=1.93 min.
