0.05g of solid 3-nitro aniline was weighed on weighing balance and then transferred to a clean iodine flask of 250 ml in which 10 ml solution of 10% sodium carbonate was already present. Mix the reaction mixture so that solid aniline got dissolved in Na2CO3 solution evenly. After that bromoacetyl bromide was added gradually and shaken vigorously for 10 minutes to prepare solid precipitates which were filtered later with proper washing. Solid precipitates were collected, weighed and saved.
