compounds for a highly specific organic reaction by molecular association. When ethylchloroacetate was treated successively with o-aminobenzenethiol (4) and chloroacetyl isocyanate (1) under mild conditions, triacylurea derivative (9) was obtained in total 84% yield. It was found that the use of “amino acid amide and oxalyl chloride” method led to the formation of diacylurea derivative (11) in high yield
