Participants

Reaction Steps

To a solution of 5-bromo-2-hydrazinylpyridine (7.1 g, 38 mmol) and 2-methoxybenzoic acid (7.0 g, 46 mmol) in dichloromethane (DCM, 100 mL) were added benzotriazole-1-yl-oxy-tris-(dimethylamino)-phosphonium hexafluorophosphate (BOP, 25.2 g, 57 mmol) and N-methylmorpholine (NMM, 13.4 g, 0.10 mol), and it was stirred at room temperature for 2 h. The mixture was filtered and the solids were washed with DCM (50 mL×3), dried to give the title compound (8.23 g, 67.5% yield) as yellow solids. MS: m/z 322.1 [M+H+].
