Abstract
1,238,977. 1 - Carbamoyl - 2 - alkoxycarbonylamino - benzimidazoles. E. I. DU PONT DE NEMOURS & CO. 28 Oct., 1969 [8 Nov., 1968], No. 52854/69. Heading C2C. Benzimidazoles of the formula wherein R is a methyl, ethyl or isopropyl group and R 1 is a C 1-8 n-alkyl group, are obtained by reacting the corresponding alkyl 2-benzimidazolecarbamates with isocyanates (R 1 NCO) in liquids selected from acetone, methylethyl ketone, 2-ethoxyethanol, dimethylformamide, dimethylacetamide, dimethylsulphoxide and methyl isobutyl ketone, optionally in admixture with water. Reference has been directed by the Comptroller to Specification 1,193,462.
