実験手順

α-(2-Acetoxy-5-sulfophenylazo)acetoacetanilide (20 g) was added to thionyl chloride (100 ml). After the addition of dimethylformamide (4 ml), solution was complete, then followed by precipitation of the product. It was filtered off and dried in the vacuum oven at 40° C. Yield: 16.7 g, m.p. 225 to 226° C.
