Reaction Steps

The title compound was prepared from 2-aminobenzimidazole, acetone and ethyl isocyanate by the procedure described in the first paragraph of Example 1. In this preparation, a 10-N-methylcarbamoyl derivative was not isolated and the subject compound was recovered from the Soxhlet extraction and recrystallized from acetone to give a solid, mp above 300° C. (dec). The confirmatory elemental analysis is shown in Table III.
