Participants

Reaction Steps

Example 1 was repeated but substituting benzyl carbazate (41.5 g, 0.25 mole) for the ethyl carbazate and using phosgene (30 ml, 0.4 mole) in diethyl ether. 2-Benzyloxyhydrazinecarbonyl chloride was isolated as a solid (53 g, 93%) mp 62°-64° C., whose ir spectrum was similar to that of 2-ethoxycarbonylhydrazinecarbonyl chloride.
