実験手順

This method was utilized to prepare the N-3 propylpurines. The starting material used was n-propyl urea condensed with ethyl cyanoacetate in the presence of sodium ethoxide to yield the 6-amino-1-propylpyrimidinedione in moderate yield. Commercially available 3-n-propylxanthine could also be used as the starting material.
