(S)-4-(2-(Dimethyl-tert-butylsilyl)oxy-3-(dibenzylamino)propoxy]benzimidazole (1.27 g. 2.5 mmol) was dissolved in methanol (140 mL) and treated with an excess of ammonium formate (1.64 g, 25.0 mmol) followed by 10% palladium on carbon (410 mg). The resulting suspension was stirred at reflux for 1 hour. After cooling, the reaction mixture was filtered through a pad of celite. The filtrate was concentrated in vacuo to a brown oil (780 mg, 97%). NMR.
