Reaction Steps

Methyl propiolate (5.75 g, 68.4 mmol) was added to methyl ethyl(tributylstannyl)carbamate (26.9 g, 68.6 mmol) in a large sealed tube. The mixture was heated to 70° C. overnight. The mixture was cooled to ambient temperature and the vial was stirred unsealed for 10 minutes. Benzyl azide (10.2 mL, 81.6 mmol) was added, and the vial was resealed and heated to 130° C. overnight. The mixture was purified by silica gel chromatography eluting with a gradient of 5-40% ethyl acetate in hexanes to afford the title compound. MS (ESI+) m/z 508.3 (M+H)+.
