24.9 g (0.1 mol) of cobalt acetate was added to 500 ml of dimethylformamide and completely dissolved. The solution was heated to 50° C., and 42.6 g (0.2 mol) of N-phenylanthranilic acid was gradually added thereto. The mixture was allowed to react for 3 hours at about 145° C. under refluxing, and the heating was terminated. The mixture, when cooled down to 100° C., was dispersed in 2 liters of water and, after 1 hour, subjected to filtration. The precipitate was washed with water until neutrality and then dried at 90° C., whereby about 40 g of pale reddish grey powder.
