Cyclohexylamine → N-[1-(t-Butylazo)cyclohexyl]-N'-cyclohexylthiourea

Participants

Reaction Steps

To 8.4 grams (0.0363 moles) of 1-t-butylazo-1-isothiocyanatocyclohexane stirred with a magnetic stirrer in a 50 ml erlenmeyer flask was added 3.6 grams (0.0363 moles) of cyclohexylamine at room temperature. A solid slowly started to form and pentane was added to keep the reaction mixture from solidifying and the reaction mixture was stirred for 3 hours and the pentane stripped off to leave a yellow solid weighing 11.4 grams (95% crude yield). The product melted at 100°-102° C. and the infrared spectrum of the product had a strong broad band at 1520-1540 cm-1 and a NH band at 3220 cm-1. The isothiocyanate band at 2040 cm-1 was absent.
