Reaction Steps

4-{[(4-Chloro-benzenesulfonyl)-((R)-5,5-dimethyl-2-oxo-azepan-3-yl)-amino]-methyl}-3-fluoro-benzoic acid (0.05 g, 0.10 mmol) was dissolved in THF (2 ml) and added dropwise to a suspension of LiAlH4 (0.04 g, 1 mmol) in THF (2 ml). After 6 h to the reaction mixture was added water (0.5 ml), 1 N NaOH (0.2 ml) and after 15 min of vigorous stirring it was filtered. The filtrate was concentrated under reduced pressure and purified using preparative RP(C18) chromatography: lyophilisate 5 mg; MS: m/e=469.1 (MH+).
