Versuchsvorschrift

Using the same procedure as in Example 1(i), 10 g of N-t-butoxycarbonyl-DL-threonine, 4.6 g of triethylamine, 5.0 g of ethyl chlorocarbonate and 4.6 g of 2-amino-1,3,4-thiadiazole were reacted in 150 ml of tetrahydrofuran to obtain 10.9 g (yield: 79%) of 2-(N-t-butoxycarbonyl-DL-threonylamino)-1,3,4-thiadiazole as white powder having a melting point of 165°-170° C. (dec.).
