反応手順
To 13 parts of methyl N-(1-amino-1-methoxymethylene)-carbamate, m.p. 36°-39.5°, prepared similar to the procedure in Example 3 for methyl N-(1-amino-1-methylthiomethylene)-carbamate in 140 parts of methylene chloride is added 15 parts of p-chlorophenyl isocyanate. The reaction mixture is stirred overnight and the solution filtered to give 10 parts of methyl 4-(p-chlorophenyl)-N-methoxycarbonylallophanimidate melting at 170° dec.
