Reaction Steps
A suspension of 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)-butoxy]-1H-quinolin-2-one (15 g) in dichloromethane (100 ml) and methanol (100 ml) was heated to 60° C., dissolved, and L(+)-tartaric acid (5.72 g) dissolved in water (10 ml) 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 L(+)-tartrate (19.3 g).
