Ethanol → 2-(1-Hydroximinoethyl)phenoxathiin

Participants

Reaction Steps

A mixture of 2-acetylphenoxathiin (J.A.C.S. 1936, 58, 717) (484 mg, 2 mmol), hydroxylamine hydrochloride (556 mg, 8 mmol), ethanol (8 mL) and pyridine (4 mL) was stirred at room temperature for 45 minutes. The ethanol was evaporated and the residue triturated with water until a solid was obtained. Filtration afforded the title oxime (465 mg) as a cream-colored solid, m.p.: 143°-148° C.
