Reaction Steps

4-Chloro-N-(5-isopropyl-2-oxo-azepan-3-yl)-benzenesulfonamide (0.06 g, 0.17 mmol), 4-bromo-methyl-benzamide (0.06 g, 0.25 mmol), K2CO3 (0.24 g, 1.7 mmol), KI (0.01 g, 0.06 mmol) were added to dry DMF (5 ml) and the resultant reaction mixture was shaken overnight at 65° C. under an argon atmosphere. The solvent was removed under reduced pressure and the residue taken up in ethyl acetate and washed with 5% KHSO4/10% K2SO4 (2×), water, brine, dried (MgSO4), filtered, concentrated under reduced pressure and purified using preparative RP(C18) chromatography: lyophilisate 23 mg; MS: m/e=478.3 (MH+), 495.4 (MNH4+)
