Benzyl Bromide → HCID 86234937, compound

Participants

Reaction Steps

359.2 g (2.0 mols+5% excess) of benzyl bromide are added dropwise to a suspension of 224.1 g (1.0 mol) of the disodium salt of glutaric acid bis-(N-cyanamide) and 1 liter of dimethylformamide at 20°-27° C. in the course of 40 minutes, the components are reacted at 68°-78° C. for 3 hours and 50 minutes and the mixture is then filtered with suction. The filtrate is concentrated on a rotary evaporator at 100° C. in vacuo and the residue is recrystallised from 800 ml of toluene. 253.7 g (70.4% of theory) of a colourless, crystalline product which has a melting point of 97.5°-100.4° C. are obtained.
