Versuchsvorschrift

This compound was prepared by a method similar to that of Müller et al. as described in Synthesis 1995, 1295. The method used was similar to that used in scheme 1 for the preparation of 3-allyl-5,6-diamino-1-butyl-1H-pyrimidine-2,4-dione except that 6-amino-3-benzyl-5-nitroso-1H-pyrimidine-2,4-dione was used as the substrate for the reaction in place of 3-allyl-6-amino-1-butyl-5-nitroso-1H-pyrimidine-2,4-dione and concentration was continued only until a solid precipitate was observed. This mixture was then cooled overnight at 0° C. and the solids isolated by filtration under an atmosphere of nitrogen to give 3-benzyl-5,6-diamino-1H-pyrimidine-2,4-dione.
