Procedure

To a solution of step 1 product (780 mg, 3.76 mmol) in THF (37.5 ml) and H2O (2.5 ml) was added NBS (670 mg, 3.76 mmol) in one portion. The solution was stirred at rt for 10 min, solvent was removed and purified on silica gel column eluting a gradient of 8-75% EtOAc in hexane to afford methyl 5-(bromoacetyl)pyridine-2-carboxylate (0.92 g) LCMS: [M+H]+=258.1, 260.1.
