Procedure

Into a 250-mL round-bottom flask were placed a solution of methyl 5-bromo-2-[2-(pyridin-2-yl)acetamido]benzoate (3 g, 7.73 mmol, 1.00 equivalent, 90%, Intermediate 61, step a) in tetrahydrofuran (30 mL). A 2.38 M solution of MeONa in MeOH (freshly prepared from dissolving 2.74 g of Na in 50 mL of anhydrous MeOH solution, 11.7 mL, 27.85 mmol, 4.00 equivalents) was then added. The resulting solution was stirred overnight at 20° C., and the precipitate was collected by filtration to give the title compound as a white solid.
