Participants

Reaction Steps

2-Aminobenzimidazole, cyclopropyl methyl ketone and methyl isocyanate were reacted as in Example 26 using THF as a cosolvent with the excess ketone. Working up the reaction mixture gave none of the expected 10-N-methylcarbamoyl derivative of the title compound but, rather, the title compound itself, recrystallized from acetone to give a solid, mp 200° C. (dec.). The confirmatory elemental analysis is shown in Table III.
