Versuchsvorschrift
N-Propyl-N'-phenylurea was prepared preliminarily from phenyl isocyanate and propylamine by the same procedure as in Reference Example 1. The urea compound as the starting material was reacted with cyanoacetic acid to form a uracil ring. Using sodium nitrite a nitroso group was introduced into the 5-position of the uracil ring in the obtained 6-amino-1-phenyl-3-propyluracil and then reduced with hydrogen gas to prepare 5,6-diamino-1-phenyl-3-propyluracil.
