Procedure

20 parts toluene, 1.74 parts (0.01 mole) 2,4-toluenediisocyanate, 2.8 parts (0.02 mole) boron trifluoride etherate and 0.40 part (0.02 mole) distilled water were combined and reacted as described in Example 1. The neutralization and isolation procedures described in Example 2 were conducted. 1.17 parts (97% yield) 2,4-toluenediamine were recovered having a melting point of 96° C.-98° C.
