Reaction Steps

Methyl 4-methoxy-3-oxobutanoate (4.28 g, 0.029 mol) was dissolved in ether (20 mL). The solution was cooled in an ice bath. To the solution was added p-toluenesulfonyl azide (5.78 g, 0.029 mol) followed by N-ethylethanamine (2.0 mL, 0.019 mol). The solution was stirred at 0° C. for 15 minutes, then at rt for 30 minutes. Upon evaporation, the tosyl amide bi-product solidified. This was filtered off and the filtrate was purified by flash chromatography to give the desired product (4.5 g, 89%) as a light oil. 1H NMR (400 MHz, CDCl3): δ 4.55 (s, 2H), 3.83 (s, 3H), 3.45 (s, 3H). MF C6H8N2O4. LCMS calculated for C6H9N2O4(M+H)+: m/z=173.0.
