Procedure

To a solution of 2-(BOC-amino)-5-bromopyridine (3.06 g) in THF (50 mL) was added sodium hydride (538 mg) and the reaction stirred at room temperature for 20 min. Then, iodomethane (0.84 mL) was added and the reaction stirred at room temperature for 16 h. The reaction was quenched with water (30 mL) and extracted into dichloromethane (3×30 mL). The organic layers were dried (MgSO4) and reduced in vacuo to give (5-bromo-pyridin-2-yl)-methyl-carbamic acid tert-butyl ester as an oil.
