Participants

Reaction Steps

Sodium thiosulfate pentahydrate (230 mg, 0.93 mmol) and silver oxide (130 mg, 0.56 mmol) were dissolved in water (5 ml) and the mixture was heated to 50° C. to 70° C. A solution of the compound (380 mg, 0.98 mmol) obtained in Step 1 in dioxane (3.5 ml) was added dropwise, and the mixture was stirred at the same temperature for 10 minutes. The reaction mixture was cooled and was acidified with an aqueous solution of diluted nitric acid and then was extracted with ether. The extract was washed with water, dried, and then the solvent was distilled off to yield the title compound (210 mg, 0.54 mmol, yield 93%).
