Participants

Reaction Steps

In 3 ml of pyridine-acetone (pyridine-acetone=2:1) were dissolved 341 mg (1 mmol) of N-(furfurylidene)-(5-fluoro-5-isobutoxycarbonyl-1,2,3,4,5,6-hexahydro-2,4-dioxopyrimidine-6-yl)amine N-oxide and 133 mg (1.2 mmol) of (E)-furfuraldoxime, and the solution was stirred at room temperature for 51 hours. The reaction solution was treated in the same manner as described in Example 9 to give 188 mg of isobutyl 5-fluoro-6-[(E)-furfurylideneaminooxy]-1,2,3,4,5,6-hexahydro-2,4-dioxopyrimidine-5-carboxylate.
