Procedure

To 50 ml of isopropanol in a 125 ml erlenmeyer flask stirred with a magnetic stirrer, was slowly added 2.1 grams (0.05 moles) of 57% sodium hydride. The reaction mixture was cooled back to 25° C. and 11.2 grams (0.05 moles) of 1-t-butylazo-1-isothiocyanatocyclohexane was added dropwise over 5 minutes. The reaction mixture was stirred for 2 hours at room temperature and then allowed to stand overnight. The next morning the reaction mixture was poured into 200 ml of water and the product extracted with 50 ml pentane. The pentane extract was washed twice with water, once with 10% NaHCO3, dried over anhydrous Na2SO4, filtered and the pentane evaporated under reduced pressure to leave a semi-solid. The semi-solid was slurried in cold pentane and filtered. The filter cake was air dried and weighed 4.0 grams (20% crude yield) and melted at 62°-64° C. The product had a strong band at 1525 cm-1 and a sharp NH band at 3300 cm-1 in its infrared spectrum.
