PROCEDURE

实验过程

A solution of 4-(N,N-di-n-hexylamino)-3-ethoxy-1,1-dioxo-1,2,5-thiadiazole (400 mg, 1.02 mmol) and L-tyrosine t-butyl ester (261 mg, 1.1 mmol) in EtOH (10 mL) was stirred at room temperature for 36 hrs. The solvent was removed under reduced pressure residue purified by flash column chromatography (silica, hexane:EtOAc 3:1 then 1:1) to give the title compound as a white waxy solid (400 mg, 73%).
