Reaktionsschritte
A 5.0 g sample of N-[2-[4-(6-fluoro-1 H-indazol-3-yl)-1-piperazinyl]ethyl]phthalimide was suspended in methanol (130 ml) and was made acidic with ethereal-HCl. After stirring for 1 hour, anhydrous ether (100 ml) was added and the suspension was stirred for an additional 30 minutes. The solid was collected and dried to afford 4.5 g of an off-white powder. This was combined with an additional sample (7.3 g total) and recrystallization from MeOH gave 4.3 g of the salt as an off-white powder, mp=265°-268° C.
