The synthesis of 2,4-diamino-4-phenoxymethylfuro[2,3-d]pyrimidin-4-one12 is shown in FIG. 20. Phenoxyacetyl chloride 10 was reacted with CH2N2 in the presence of gaseous hydrogen chloride and ether to produce 1-chloro-3-phenoxy-2-propanone 11. 1-chloro-3-phenoxy-2-propanone 11 was reacted with 2,6-diamino-3H-pyrimidin-4-one 1 to produce 2,4-diamino-4-phenoxymethylfuro[2,3-d]pyrimidin-4-one 12 at a 39% yield.
