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 malonic acid (0.53 g) dissolved 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 malonate (2.4 g).
