Procedure

2-Fluoroethylamine hydrochloride (50 mg) and the compound prepared in Example 222 (88 mg) were dissolved in dimethylformamide (1 ml), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydro-chloride (86 mg), 1-hydroxybenzotriazole (77 mg), and dimethylaminopyridine (5 mg) were added to the solution. The reaction mixture was stirred at room temperature for 18 hr. A saturated aqueous sodium hydrogencarbonate solution (1 ml) was then added thereto, and the mixture was extracted with chloroform-propanol (3/1). The organic layer was dried over anhydrous sodium sulfate, and the solvent was removed by distillation under the reduced pressure. The residue was purified by HPLC [chloroform/methanol] to give 39 mg of the title compound as two diastereomers (ratio=ca. 50:50).
