Procedure

A mixture of 6-[(1-carbamoyl-1,2-dimethylpropyl)carbamoyl]-1,2-dimethyl-5-benzimidazolecarboxylic acid (0.330 g, 0.910 mmol) and 2M sodium hydroxide (3.0 mL, 6.0 mmol) is stirred for 2.5 hours at reflux temperature, cooled, acidified to pH 3 with hydrochloric acid and filtered. The filter cake is recrystallized from ethanol to afford the title product as a white solid (0.120 g, 31.5%), mp 256°-258° C.
