Participants

Reaction Steps

The 4-methoxycarbonyl-2'-methoxybenzanilide (123.2 g) obtained in (1) was dissolved in 400 ml of toluene, and 96.1 g of Lawesson's reagent was added. The mixture was refluxed for 2 hours. After the reaction, the reaction mixture was hot-filtered. The filtrate was left to stand until it cooled to room temperature. The precipitated crystals were collected by filtration and washed with a small amount of benzene to give 69.2 g of 4-methoxycarbonyl-2'-methoxybenzothioanilide.
