After cooling to 0° C., the whole was treated with a sodium hydroxide solution. The product was extracted with dichloromethane. The extract was washed with water, dried, filtered and evaporated, yielding 34.5 parts (45%) of 3-[[3-(trifluoromethyl)phenyl]amino]propanenitrile as a residue (int. 105).
