参加物

反応物 2

HCID 89023Methyl N-cyanocarbamate

HCID 544798772-Nitro-5-cyclohexylethylthioaniline

生成物 1

HCID 544156975-Cyclohexylethylthio-2-carbomethoxyaminobenzimidazole

実験手順

Repeating the reaction of Example 1 but using 10.0 g. of cyclohexylethylthiol gives 2-nitro-5-cyclohexylethylthioaniline. The nitro compound is reduced. The reduction mixture is reacted with carbomethoxycyanamide as described to give 5-cyclohexylethylthio-2-carbomethoxyaminobenzimidazole.
