반응 단계
A solution of 5.0 parts of the salt of methyl cyanocarbamate with o-phenylenediamine and 1.5 parts of acetic acid in 25 parts of water is refluxed for 30 minutes. The solution is cooled to 50° C. and filtered. The product is washed with water and dried in vacuo at 95° C. This procedure gives 3.3 parts (72% yield) of 2-benzimidazolecarbamic acid, methyl ester.
