実験手順
Following the procedure of Example 2, 5-chloroisatoic anhydride (19.8 g., 0.1 mole), malononitrile (7.3 g., 0.11 mole) and triethylamine (11.1 g., 0.11 mole) are reacted together in N,N-dimethylformamide (200 ml.) to give 20 g. of product. Five grams of said product are refluxed for 22 hours in 48% hydrobromic acid (175 ml.) to give 4.2 g. (86%) yield of title product; m.p. 356° C. (dec.).
