Procedure

After adding 100 g of manganese dioxide to a solution of 27.2 g of the crude product of 2-(8-methoxy-4H-benzo[1,3]dioxin-6-yl)-2-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamino]thioacetimidic acid methyl ester in 100 ml of ethyl acetate, the mixture was stirred at room temperature for 1 hour. The reaction mixture was filtered through celite, and the filtrate was concentrated under reduced pressure to give the title compound (23.8 g, crude product) as a brown solid.

Workup

  1. filtrationThe reaction mixture was filtered through celite
  2. concentrationthe filtrate was concentrated under reduced pressure
