Reaction Steps
To a solution of 689 mg (10.13 mmol) sodium ethoxide in 5 mL absolute ethanol at 0° C. was added a solution of 500 mg (2.44 mmol) of allyl 4-formylphenylcarbamate and 1.25 g (9.75 mmol) ethylazidoacetate dissolved in 5 mL absolute ethanol and 1 mL tetrahydrofuran dropwise over 5 minutes. The mixture was stirred at 0° C. for 1.5 h, then partitioned between ethyl acetate and 1 N HCl until neutral. The organic phase was dried over magnesium sulfate, concentrated and purified by column chromatography, eluting with 25% ethyl acetate/hexane to provide 385 mg of ethyl (2E)-3-(4-{[(allyloxy)carbonyl]amino}phenyl)-2-azidoprop-2-enoate as a yellow solid.
