A solution of pentafluorophenyl 5-[(E)-3-(imidazol-1-yl)prop-1-en-1-yl]-2-(4-fluorophenethyl)benzoate (0.36 g, 0.7 mmol), L-methionine-tert-butyl ester(0.173 g, 0.84 mmol) and 1-hydroxy-7-azabenzotriazole (0.1 g, 0.73 mmol) in DMF (2 ml) was stirred at ambient temperature overnight. After evaporation of the solvent, the residue was taken up in ethyl acetate, washed with 5% sodium hydrogen carbonate solution and saturated brine and evaporated to dryness. The residue was then purified by flash chromatography eluting with dichloromethane/ethanol (97/3) to give the title compound. Yield: 50%
