Participants

Reaction Steps

Fumaric acid was added to an ethanol solution of 7-[(3-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)propoxy]-2-methyl-3,4-dihydro-2H-isoquinolin-1-one and the solvent was evaporated under reduced pressure. The residue was recrystallized from 90% ethanol and thereby 7-[3-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)propoxy]-2-methyl-3,4-dihydro-2H-isoquinolin-1-one difumarate was obtained in the form of white prism crystal.
