Cyclohexylamine → HCID 21387400, compound

Participants

Reaction Steps

To 5.3 grams (0.025 moles) of stirred 2-sec.-butylazo-2-isocyanato- 4-methylpentane (from Example XVII) in a 50 ml erlenmeyer flask was added 2.6 grams (0.026 moles) of cyclohexylamine. A solid quickly formed so 25 ml of pentane was added and the slurry stirred for approximately 1/2 hour, the solid filtered, reslurried in 25 ml of fresh pentane and refiltered. The solid was air dried and weighed. The white powder weighed 4.4 grams (57% crude yield) and had a melting range of 118° to 123° C. The infrared spectrum of the product was in agreement with the structure of N-[ 1-(sec.-butylazo)- 1,3-dimethylbutyl]-N'-cyclohexylurea (sharp NH at 3250 cm-1 and strong carbonyl band at 1625 cm-1).
