Participants

Reaction Steps

12 Parts ethoxycarbonyl isocyanate was added dropwise to 23 parts of methyl 4-(4-chlorophenyl)allophanimidate (prepared as above) in 230 parts of tetrahydrofuran at 20°C. The mixture was stirred for six hours at room temperature and then evaporated under reduced pressure. The residue was triturated with boiling 1-chlorobutane, cooled, and the solid collected by filtration affording 16 parts of ethyl 4-[1-(4-chlorophenylcarbamoylimino)-1-(methoxy)methyl]allophanate, m.p. 140.5-142°C.
