Reaction Steps

Into a 250-mL round-bottom flask was placed a solution of methyl 2-amino-5-bromobenzoate (5 g, 21.73 mmol, 100%), 2-(pyridin-3-yl)acetic acid hydrochloride (4.5 g, 25.92 mmol), HATU (10 g, 26.30 mmol 100%) and DIEA (8.5 g, 65.77 mmol, 100%) in N,N-dimethylformamide (100 mL). The resulting solution was stirred overnight at 20° C. The reaction was then quenched by the addition of 100 mL of water. The resulting solution was extracted with 3×100 mL of dichloromethane and the organic layers combined and dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:2-1:1) to provide the title compound as a yellow solid.
