Versuchsvorschrift

The compound (600 mg, 2.33 mmol) obtained in Example 89a and tert-butyl methyl[2-(methylamino)ethyl]carbamate (439 mg, 2.33 mmol) described in the literature (J. Med. Chem. 1990, 33, 97) were dissolved in methylene chloride (23 mL), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (670 mg, 3.50 mmol) and 4-dimethylaminopyridine (14 mg, 0.117 mmol) were added, and the mixture was stirred at room temperature for 1.5 hours. The solvent was evaporated under reduced pressure, 1 N hydrochloric acid was added to the resulting residue, the mixture was extracted with ethyl acetate, and then the organic layer was washed with saturated sodium chloride solution. The organic layer was dried with anhydrous sodium sulfate, then the solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:1, v/v) to give the title compound (757 mg; yield, 79%) as a light yellow solid.
