Procedure

A mixture of 1-benzyl-4-[(1-carbamoyl-1,2-dimethylpropyl)carbamoyl]-2-methyl-5-benzimidazolecarboxylic acid (3.58 g, 8.47 mmol), 10N sodium hydroxide (5.08 mL, 50.8 mmol) and water is stirred for 4 hours at reflux temperature, cooled, acidified to pH 4 with hydrochloric acid and filtered. The filter cake is recrystallized from acetonitrile to give the title product as an off-white powder (1.06 g, 31.0%), mp 198°-208° C. (dec).
