Reaction Steps

A 5.0 g sample of N-[2-[4(6-fluoro-1H-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.
