Participants

Reaction Steps

Sodium hydroxide (0.17 g), ethanol (8 ml), and water (4 ml) were added to 1-(4-butyloxy2-chlorobenzyl)(ethoxycarbonyl)-2-methylbenzimidazole (0.62 g) and the whole was s d for 4 hours at 80° C. The pH was adjusted to about 5 with 35% hydrochloric acid. Deposited crystals were filtered and dried to obtain crystals (0.42 g) of 1-(4-butyloxy-2-chlorobenzyl)-6-carboxy-2-methyl-benzimidazole.
