Reaction Conditions

Reaction Steps

266.41 g (1.183 mol) of 1-(3-fluorophenyl)-3,4-dihydroisoquinoline were dissolved in 1500 ml of o-dichlorobenzene and admixed with 901.2 g (10.37 mol, 8.7 eq.) of manganese. The mixture was stirred at 160-170° C. for 16 h. Subsequently, the reaction solution was filtered through Celite which was rinsed with dichloromethane/ethanol (25:1). Subsequently, the solvent was distilled off under reduced pressure. 264.74 g of a crystalline solid with 99% purity were obtained, corresponding to 99% of theory.
