2-Nitrobenzenesulfonyl chloride → o-Nitrobenzenesulfonyl Azide

Participants

Reaction Steps

To a solution of 15.0 g (0.069 mole) of o-nitrobenzenesulfonyl chloride dissolved in 150 ml ethanol was added 5.89 g (0.090 mole) of sodium azide dissolved in a minimum amount of water. The solution was stirred for 30 minutes and then poured into a 2 liter Erlenmeyer flask containing 500 ml of ice water. The resultant white solid was filtered, dried and recrystallized from ethanol. The purified product had a melting point 73°-74° C. (lit. 73°-74° C.) and was isolated in 92% yield (14.47 g).
