Hydrogen Peroxide → HCID 178507181, compound

Participants

Reaction Steps

Twenty grams of adenosine with a product code of A9251-25G, commercialized by Sigma-Aldrich Japan K.K., Tokyo, Japan, was dispersed in one liter of acetic acid and admixed with 100 mL of 30% hydrogen peroxide solution, followed by stirring the resulting mixture at ambient temperature for five days. An excessive amount of the remaining hydrogen peroxide was decomposed by the addition of five grams of 5% palladium carbon, commercialized by Kawaken Fine Chemicals Co., Ltd., Tokyo, Japan, followed by filtering the mixture to remove the palladium carbon, drying the resulting solution in vacuo, adding ethanol to the dried product to disperse the formed crystals, and filtering the resulting mixture to obtain crude crystals of adenosine N1-oxide. Eight grams of adenosine N1-oxide with a purity of 99.5% was obtained by dissolving the crude crystals in ethanol by heating, filtering the resulting solution, ice-chilling the filtrate to effect recrystallization, and repeating these steps twice.
