Methanol → (1S)-1-(5-chloro-1H-benzimidazol-2-yl)-3-(1H-tetrazol-5-yl)propylamine

Participants

Reaction Steps

2.10 g (4.45 mmol) (1S)-N-(benzyloxycarbonyl)-1-(5-chloro-1H-benzimidazol-2-yl)-3-(1H-tetrazol-5-yl)-propylamine in 30 ml dichloromethane are combined with 1.9 ml (13.4 mmol) iodo-trimethylsilane and stirred for 16 hours at ambient temperature. Then 20 ml of methanol are added, the mixture is stirred for a further 30 minutes at ambient temperature and the reaction mixture is evaporated down completely i. vac. The residue is purified by chromatography on silica gel (eluting gradient: dichloromethane/(ethanol/conc. ammonia 95:5)=70/30->60:40).
