Reaktionsschritte

To 9.1 grams (.0394 moles) of 1-t-butylazo-1-isothiocyanatocyclohexane stirred with a magnetic stirrer in a 50 ml erlenmeyer flask was added 2.88 grams (.0394 moles) of isobutylamine at room temperature. The reaction mixture became viscous so pentane was added and the reaction was stirred an additional 4 hours and the pentane stripped off to leave a yellow solid weighing 11.6 grams (97% crude yield). The product melted at 90°-93° C. and the infrared spectrum of the product had a strong broad band at 1520-1550 cm-1 and a NH band at 3270 cm-1. There was only a trace of the isothiocyanate band at 2040 cm-1 which was present in the starting material.
