Reaction Steps

To a solution of 2-(BOC-amino)-5-bromopyridine (500 mg) in THF (20 mL) at 0° C. was added sodium hydride (88 mg) and the reaction stirred for 20 min. Then, iodoethane (0.18 mL) was added and the reaction stirred at room temperature for 16 h. The reaction was quenched with water (20 mL) and extracted into ethylacetate (3×20 mL). The organic layers were dried (MgSO4) and reduced in vacuo to give (5-bromo-pyridin-2-yl)-ethyl-carbamic acid tert-butyl ester as a white solid.
