실험 절차

To 93 mg (0.20 mmol) of di-tert-butyl (4S)—N-(tert-butoxycarbonyl)-4-(4-hydroxybenzyl)-L-glutamate (Example 1b) in 9 mL N,N-dimethylformamide were added 60.7 mg (0.44 mmol) of powdered potassium carbonate and 45 mg (0.24 mmol) of 1-iodo-3-fluoropropane (ABCR GmbH, Germany) and the resulting suspension was stirred for 5 h at 60° C. and overnight at room temperature. The reaction mixture was than filtered, the solvent evaporated and the residue was taken up in ethyl acetate and water. The organic phase was separated off, washed with water until neutral, dried over sodium sulfate and filtered, and the filtrate was concentrated in vacuo. The crude product obtained in this manner was chromatographed on silica gel using a dichloromethane/methanol gradient, and the appropriate fractions were combined and concentrated.
