6-Methyl-1H-benzimidazole-2-methanol Use and Manufacturing

(5-Methyl-1H-benzimidazole-2-yl)-methanol 25 was prepared using the Phillips procedure [1], 4-Methyl-1, 2-phenylenediamine (12.22 g; 0.1 mol) and glycolic acid (11.40 g; 0.15 mmol) in hydrochloric acid (50 ml, 5.5 M) were heated under reflux with for 3 h. The reaction mixture was cooled to room temperature and ammonia solution was added and the mixture cooled in ice until a bright brown precipitate formed. The resulting solid was recrystallised from aqueous ethanol to give (5-methyl-1H-benzimidazole-2-yl)-methanol as a pale creamy powdery solid Yield 100percent.General procedure: To a mixture of 1a–1c (10 mmol) with glycolic acid (2.28 g, 30 mmol) was added concentrated H3PO4(20 mL). The reaction mixture was refluxed at 130°C for 3 h, then quenched with 20percent NaOH. The respective solid product was collected by filtration.Step 1
