Good quality 4-Nitrobenzyl bromide CAS 100-11-8
4-Nitrobenzyl Bromide is used in the synthesis of di and tri-substituted azoles. Also used in the preparation of N6-Benzyladenosine-5`-uronamides as selective A3 adenosine agonists.
1. Preparation method: In a reaction flask equipped with a stirrer, a thermometer, a reflux condenser (with a gas pipe to absorb hydrogen bromide), dropping funnel, add p-nitrotoluene
(2) 150 g (1.1 mol) was heated to 145-150° C. under stirring and slowly added dropwise 184 g (1.15 mol) of bromine, and the addition was completed in 2 hours. After the addition was complete, the reaction was continued for 10 minutes. After slightly cold, it is poured into 2L of hot petroleum ether (80-100°C), activated charcoal is added and refluxed for 10 min. After hot filtration, cool to about 20°C, filter out crystals, wash with petroleum ether, and dry to obtain crude p-nitrobenzyl bromide.
(1) 150 g, mp 95-97°C. Recrystallization from petroleum ether, mp 98-99°C, yield 135 g, yield 57%.
For organic analysis reagents, dye intermediates.
