Reaction Steps

A suspension of 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)-butoxy]-1H-quinolin-2-one (2 g) in dichloromethane (20 ml) and methanol (20 ml) was warmed to 60° C., dissolved, and a solution of 47% hydrobromic acid (0.86 g) in methanol was added at room temperature. The precipitated crystals were collected by filtration, and dried to give 7-[4-(4-Benzo[b]thiophen-4-yl-piperazin-1-yl)-butoxy]-1H-quinolin-2-one hydrobromide (2.2 g).
