Procedure

Sodium hydride (60% in oil, 140 mg, 3.40 mmol) was added to a solution of methyl 2-(((2-amino-5-bromopyridin-3-yl)methyl)(4-methoxybenzyl)amino)acetate (1.05 g, 2.66 mmol) in DMSO (17 mL) at room temperature. The reaction mixture was stirred overnight then diluted by addition of water (45 mL). After 2 hours stirring at room temperature, the reaction mixture was filtered. The resulting solid was dried under high vacuum to give the title compound as a yellow solid (600 mg, 63%)
