Phenacyl bromide → HCID 54398312, compound

Participants

Reaction Steps

3-Hydroxy-2-n-tetradecyl-octadecanoic acid (II) prepared as described [Bulletin de la Societe chimique de France 504-510 (1954)] was dissolved in dry tetrahydrofuran (45 ml), and then phenacyl bromide (2.70 g, 13.59 millimole) and triethyl amine (1.89 ml, 13.59 millimole) were successively added thereto with ice cooling. The mixture was allowed to warm to the room temperature, and reacted for 23 hours. The insoluble mass in the reaction mixture was filtered off with suction and the solvent was distilled from the filtrate. The residue was dissolved in benzene and the obtained solution was fractionated through silicagel column chromatography (benzene). After the fractions comprising impurities were discarded, the later colorless fractions were pooled, and the solvent was distilled off from the fraction to, give white crystals of phenacyl 3-hydroxy-2-n-tetradecyl-octadecanoate (IV) (1.81 g, yield 33%).
