Reaction Steps

Combine t-butoxycarbonylaminomalonic acid (0.465 g, 2.12 mmol), phenethylamine (0.715 mL, 5.70 mmol), and dichloromethane (25 mL). Add N-methylmorpholine (0.752 mL, 6.85 mmol). Cool in an ice bath. Add benzotriazol-1-yloxy-tris(pyrrolidino)phosphonium hexafluorophosphate complex (3.15 g, 6.85 mmol). Remove the ice bath and allow to warm to ambient temperature. After 18 hours, dilute the reaction mixture with ethyl acetate, extract with an aqueous 5% sulfuric acid solution, a saturated sodium bicarbonate solution, and then brine. Dry the organic layers over Na2SO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with 2/1 ethyl acetate/hexane to give the title compound.
