Hydrogen Bromide → HCID 13533275, compound

Participants

Reaction Steps

To 10 ml of dioxane solution containing 5 g of 1-(cyclopropyl, hydroxymethyl)-4-methylthiobenzene was added dropwise 6 ml of 47% of hydrobromic acid under an ice-cooled condition, then the mixture was stirred for 30 minutes, and the reaction mixture was concentrated under a reduced pressure. To the residue thus obtained was added water, then extracted with ether, the extract was washed with water and dried with anhydrous sodium sulfate, and concentrated to dryness. The residue was recrystallized from methanol to yield 2.2 g of 4-(4'-methylthiophenyl)-3(E)-butenylbromide in the form of colorless flake-like crystals. Melting point: 54°-56° C.
