Bromine → HCID 23119266, compound

Participants

Reaction Steps

To a 10% methanol-chloroform (60 mL) solution of 5-(3-methyloxyhexyl)tetralone (6) (9.0 g) was added bromine (5.5 g), and the reaction mixture was stirred for 1 h. After the solvent was evaoprated, the residue was dissolved in ethanol (60 mL), and to the residue was added thiourea (2.65 g). After the mixture was heated at reflux for 7 h, the reaction solvent was evported. To the residue was added a saturated sodium hydrogencarbonate aqueous solution, and the mixture was extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, and evaporated. The obtained residue was purified by column chromatography (hexane:ethyl acetate=4:1) to obtain the compoumd (7) 4.6 g.
