To 22.65 grams (0.1 mole) of 2-t-butylazo-2-isothiocyanato-4-methylpentane stirred with a magnetic stirrer in a 125 ml erlenmeyer flask was slowly added 7.7 grams (0.105 mole) of n-butylamine. After the addition was complete, the reaction mixture was stirred for 3 hours at 30° C., dissolved in pentane, transferred to a round bottom flask and the pentane evaporated under reduced pressure. The residue was then stripped under high vacuum to remove any low boilers. The residue weighed 30 grams (100% yield) and its infrared spectrum contained peaks around 1500-1550 cm-1 which appears to be due to the ##STR56## group and NH peaks around 3350 cm-1. The isothiocyano band around 2040 cm-1 had disappeared.
