Reaction Steps

By a similar method as in Example 1, 2-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butyl]-3,4-dihydro-2H-isoquinolin-1-one was prepared from 2-(4-chlorobutyl)-3,4-dihydro-2H-isoquinolin-1-one, and after it was made into an ethanol solution, 1N hydrochloric acid ethanol solution was added thereto, precipitated crystals were separated by filtration, recrystallized from a mixed solvent of isopropyl alcohol-ethanol and thereby 2-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butyl]-3,4-dihydro-2H-isoquinolin-1-one hydrochloride was obtained.
