Hydrogen chloride-ethyl acetate → HCID 67536685, compound

Participants

Reaction Steps

To (2-benzoyl-3-methylphenyl)acetonitrile (4.6 g) were added EtOH (70 mL), 4 M HCl/EtOAc (15 mL), and platinum oxide (IV) (0.40 g), followed by stirring under a hydrogen atmosphere for 3 days. The reaction liquid was filtered through celite and then concentrated. Toluene was added to the concentrate, followed by extraction with an aqueous 1 M HCl solution. A 28% aqueous ammonia solution was added to the aqueous layer, which was then extracted with toluene and dried over magnesium sulfate. The solvent was evaporated and the residue was dissolved in toluene. 4 M HCl/EtOAc (7 mL) was added to the mixture, followed by concentration under reduced pressure. iPrOH and diisopropyl ether were added to the resulting residue, and the precipitated solid was collected to obtain 1-cyclohexyl-8-methyl-3,4-dihydroisoquinoline hydrochloride (2.2 g).
