実験手順

A solution of 3,4-diethyloxy-1,1-dioxo-1,2,5-thiadiazole (400 mg, 1.94 mmol)and L-tyrosine t-butyl ester (1.25 g, 5.2 mmol) in ethanol (25 mL) was stirred at room temperature overnight. Solvent was removed under reduced pressure and the product used in further transformations without further purification (Yield 790 mg).
