実験手順
60 mg (0.11 mmol) of di-tert-butyl (4R)—N-(tert-butoxycarbonyl)-4-[4-(3-fluoropropoxy)-benzyl]-D-glutamate were taken up in 3 mL of trifluoro acetic acid and stirred overnight at room temperature. The excess of trifluoro acetic acid was evaporated and the residue was taken up three times in tetrahydrofuran and then evaporated. The resulting oil was chromatographed on C-18 reversed phase silica gel using a water/acetonitrile gradient, the appropriate fractions were combined and concentrated.
