To a solution of 90 grams (0.316 moles) of butyl levulinate t-amylhydrazone in 150 mls. of petane in a 500 ml. round bottom flask was passed 10.9 grams (.154 moles) of chlorine holding the temperature at -20°C with a dry ice- isopropanol bath. The chlorine was added over 30 minutes and then the reaction was stirred an additional 15 minutes at -20°C and filtered. The filtrate was dried and the pentane evaporated leaving 46.6 grams of crude butyl 4-t-amylazo-4-chlorovalerate.
