Reaction Steps

0.2 g of 3-[(1,2-diphenyl-1H-benzimidazol-6-yl)oxy]propan-1-ol was suspended in 1.7 ml of toluene and 0.7 ml of tetrahydrofuran. 60 μl of acrylic acid-tert-butyl ester, 13 mg of tetrabutylammonium hydrogen sulfate, and 1.47 ml of 32% sodium hydroxide solution were added to it, and it was allowed to stir for 48 hours. Another 60 μl of acrylic acid-tert-butyl ester and 13 mg of tetrabutylammonium hydrogen sulfate were added, and the mixture was left for 48 hours in an ultrasound bath. Then, it was diluted with water and extracted three times with toluene. The combined organic phases were washed with water and saturated sodium chloride solution, dried on sodium sulfate and concentrated by evaporation in a vacuum. The residue was chromatographed on silica gel.
