Reaction Steps
Example 1 was repeated but substituting iso-butyl carbazate (24.75 g, 0.6 mole) for the ethyl carbazate and using phosgene (20 ml, 0.3 mole) in diethyl ether. 2-(2-methylpropyloxycarbonyl)hydrazinecarbonyl chloride was isolated as a viscous oil (31 g, 84%) whose ir spectrum was similar to that of 2-ethoxycarbonylhydrazinecarbonyl chloride.
