Reaction Steps

5-Phenyl-3-ureidofuran-2-carboxylate 41 (125 mg, 1.0 eq) was suspended in methanol (5 ml) and treated with 1.5 M NaOH (1 ml). Reaction mixture was heated to reflux for 90 minutes. Reaction mixture was allowed to cool down to room temperature, and was acidified with 6N HCl up to pH 3. Solid was filtered and dried at 95° C. under high vacuum for 24 h to yield 6-phenylfuro[3,2-d]pyrimidine-2,4-diol (79 mg, 76%) as a beige solid which was used in the next reaction without further purification.
