Reaction Steps

To a solution of sodium metal (0.6 g) in n-propyl alcohol (200 mL) was fed gaseous ammonia at a flow rate of 120 mL/min. at room temperature for 1 hour. Then, 27.0 g of 4-(2-aminophenylthio)-5-(4-tert-butylphenylthio)-3,6-diisopentoxyphthalonitrile was added and the mixture was stirred at 50-60° C. for 20 hours. After cooling, the reaction mixture was worked up in the same manner as in Example 1 to provide 20.9 g (yield 75.2%) of 5-(2-aminophenylthio)-6-(4-tert-butylphenylthio)-1,3-diimino-4,7-diisopentoxyisoindoline of the following chemical formula. ##STR12##
