Reaction Steps

3 g (0.013 mol) of 4-chlorophenyl tert.-butyl ketone N-methylhydrazone was dissolved in 30 ml methylene chloride and treated with 1.5 g triethylamine (0.014 mol). Then, at 0° C., 1.33 g (0.014 mol) methyl chloroformate was added dropwise and the mixture stirred for one hour. The reaction mixture was then treated with water and methylene chloride and the organic phase dried and concentrated. After thin layer chromatography, there was obtained methyl 3-[1-(4-chlorophenyl)-2,2-dimethylpropylidene]-2-methylcarbazate, m.p. 58°-60° C.
