Reaction Steps

2,5,6-Trimethylbenzimidazole (9.4 g) and sodium hydride (2.1 g, 80% suspension in oil) were sonicated in dry tetrahydrofuran (150 ml) for 1 hour. Ethyl 2-bromoacetate (9.8 g) in dry tetrahydrofuran (50 ml) was added and the reaction sonicated at 40° C. for 2 hours. The reaction was partitioned between ethyl acetate (300 ml) and water (100 ml), the organic phase dried over magnesium sulphate and the solvent removed under reduced pressure to yield ethyl 2-(2,5,6-trimethylbenzimidazol-1-yl)acetate (13.5 g).
