Reaction Steps

2-(3-amino-4-methoxyphenyl)-3-(4-nitrophenyl) propionic acid (6.20 g, 19.6 mmol) was dissolved in a mixed solvent of acetone (50 mL) and water (50 mL), and was gradually added with an acetone solution (50 mL) of 9-fluorenylmethyl chloroformate (5.08 g, 19.6 mmol) over 30 minutes in a drop-wise manner at 0° C. The mixture was heated to room temperature, and further stirred for 3 hours. The mixture was then added with dichloromethane (200 mL) and water (300 mL). The separated aqueous phase was extracted with dichloromethane (150 mL) three times. The extracts were mixed with the first organic phase, and washed twice with a saturated brine (150 mL). The organic phase was dried over sodium sulfate, evaporated under reduced pressure so as to remove the solvent, to thereby obtain N-fluoronylmethoxy carbonyl-2-(3-amino-4-methoxyphenyl)-3-(4-nitrophenyl) propionic acid (yield: 10.3 g, yield ratio: 97%).
