Procedure
Into a 250-mL round-bottom flask was placed a solution of methyl 2-amino-5-bromobenzoate (5 g, 21.73 mmol), 2-(pyridin-2-yl)acetic acid hydrochloride (4.5 g, 25.92 mmol), HATU (10 g, 26.30 mmol) and DIEA (8.5 g, 65.77 mmol) 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, filtered and concentrated under vacuum. The residue was applied onto a silica gel column with dichloromethane/methanol (1:50) to afford the title compound as a red solid.
