Reaction Steps

After dissolving 1-[2-[(1-naphthalen-1-ylmethyl-piperidin-4-ylmethyl)-(2-trimethylsilanyl-ethoxymethyl)-amino]-1-(2-trimethylsilanyl-ethoxymethyl)-1H-benzimidazol-5-yl]-propan-1-ol (50 mg, 0.073 mmol) in anhydrous dimethylformamide (2 ml), tetrabutylammonium fluoride (0.5 ml, 1.0 M tetrahydrofuran solution) was added and the mixture was stirred at 100° C. for 13 hours. Ethyl acetate and water were added, after which the aqueous layer was adjusted to pH 11 and extracted with ethyl acetate. The organic layer was washed with saturated brine and then dried over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure, and the obtained residue was purified by thin-layer silica gel chromatography (ethyl acetate/methanol=4/1). The purified product was further purified by preparative HPLC to obtain 1-{2-[(1-naphthalen-1-ylmethyl-piperidin-4-ylmethyl)-amino]-1H-benzimidazol-5-yl}-propan-1-ol.
