Peracetic Acid → HCID 178502003, compound

Participants

Reaction Steps

6.75 ml of 40% peracetic acid are added dropwise at 0° to a suspension of 3.4 g (10 mmol) of methyl 2-amino-6-([p-toluenesulfonyl)oxy]-4-pyrimidinecarbamate in 120 ml of absolute ethanol. The mixture is stirred at room temperature for 48 hours and thereafter poured into an aqueous solution of sodium sulfite. Ethyl acetate is added thereto, the organic phase is separated, dried over sodium sulphate and evaporated under reduced pressure. The residue is recrystallized from methylene chloride/methanol, there being obtained methyl 2-amino-6-[(p-toluenesulfonyl)oxy]-4-pyrimidinecarbamate-3-oxide of melting point 144°-145°.
