ABSTRACT:
Racemic 1-(4-methoxybenzyl)-1,2,3,4,5,6,7,8-octahydroisoquinoline can be resolved by seeding the supersaturated solution of racemic 1-(4-methoxybenzyl)-octahydroisoquinolinium acetate with its enantiomeric forms and crystallizing the optically active acetate corresponding to the configuration of the seed crystals. The continuous form of the process permits obtaining the two enantiomers together.
