Versuchsvorschrift

A solution of the amine of Example 43 (98 mg, 0.30 mmol) in dimethylformamide (3.75 ml) was treated with benzoic acid (41 mg, 0.33 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (64 mg, 0.33 mmol) and 4-dimethylaminopyridine (81 mg, 0.66 mmol) and stirred at room temperature for 18 hours. The solution was concentrated under reduced pressure. The residue was partitioned between dichloromethane and saturated sodium hydrogencarbonate solution. The organic extract was dried over anhydrous magnesium sulphate, filtered and concentrated under reduced pressure. The crude material was purified by flash chromatography on silica gel eluting with dichloromethane:methanol (95:5, by volume) to afford the title compound (48 mg) as a white solid, m.p. 115–117° C.
