実験手順
To a stirred solution of 3.95 grams (0.054 moles) of diethylamine in 30 ml pentane in a 50 ml erlenmeyer flask cooled in a water bath was added 6.05 grams (0.027 moles) of 2,2'-azobis(2-isocyanatobutane) (from Example XXXVI) dropwise over 20 minutes while holding the reaction temperature below 30° C. After the addition was complete, the reaction was stirred for an additional 60 minutes at room temperature and filtered. The filter cake was washed with pentane and dried. The dry white solid weighed 1.8 grams (18% crude yield) and melted at 215°-220° C. with decomposition. The product had a broad carbonyl band at 1650 cm-1 and a strong NH band at 3400 cm-1 in its infrared spectrum and the isocyanate band at 2200 cm-1 was absent.
