Procedure
This compound was prepared in a manner analogous to that of Example 1, using 4.2 grams (0.05 mole) of cyanoguanidine and 13.1 grams (0.08 mole) of 4-phenylcyclohexanone. The crude product was recrystallized from ethanol, yielding 2,4-diamino-6-phenyl-5,6,7,8-tetrahydroquinazoline, mp 223°-226° C. The NMR spectrum was consistent with the proposed structure.
