Participants

Reaction Steps

A solution 1.25 g (2.4 mmole) of (2,5-difluorophenyl)-N-propyl-N-({1-propyl-5-[(1,1,2,2-tetramethyl-1-silapropoxy)methyl]benzimidazol-2-yl}methyl)carboxamide in 20 mL of THF is treated at room temperature with 3 mL of 1M tetrabutylammonium fluoride for 1 hr. The reaction solution is diluted with 20 mL of sat NaHCO3 and extracted with 3×100 mL of dichloromethane. The organic extracts are dried over anhydrous Na2SO4 and the solvent removed in vacuo to afford 0.96 g (99%) of (2,5-difluorophenyl)-N-{[5-(hydroxymethyl)-1-propylbenzimidazol-2-yl]methyl}-N-propylcarboxamide.
