To a solution of methyl 3-[(3-methoxy-3-oxopropanoyl)amino]pyridine-2-carboxylate (7.3 g, 29.9 mmol, prepared as described in example 1) in anhydrous TBF (100 mL) was added solid sodium methoxide (3.9 g, 72.4 mmol) at 0° C. Immediately following the addition of the sodium methoxide, solids crashed out of the solution. The ice bath was then removed and the suspension was stirred for an additional 0.5 hours. The suspension was then filtered through a medium porosity filtration funnel to afford yellow solids.
