실험 절차

The suspension of mixed anhydride in THF is prepared by using 1.78 g of (2R,4R)-3-(S-acetyl-3-mercaptopropanoyl)-2-(2-hydroxyphenyl)-4-thiazolidinecarboxylic acid, 0.51 g of N-methylmorpholine and 0.68 g of isobutyl chlorocarbonate. To the suspension the aqueous solution of 1.31 g of L-leucine and 1.0 g of triethylamine is added, and treated in the same manner as Example 1 to give 1.8 g (77%) of the titled compound.
