Reaction Steps

0.76 g of hydroxylamine hydrochloride was added to a stirred solution of 0.72 g of 85% aqueous potassium hydroxide in 25 ml of absolute ethanol at room temperature. The mixture was stirred at room temperature for 20 minutes, then 1.55 g of 27C was added and the mixture was heated at reflux for 3 hours, held overnight at room temperature, and filtered. The filtrate was stripped of solvent to give a dark oil, from which a yellow solid precipitated on standing. The solid was separated, and stirred in hot ethyl acetate. The resulting mixture was filtered, the solvent was stripped from the filtrate and the residue was recrystallized from ethanol to give 27, as a yellow solid, m.p.: 223° C.
