Versuchsvorschrift

To a mixture of 2-chloromethyl-4-phenoxy-benzoic acid methyl ester (17.8 g, 64.3 mmol) in DMF (100 mL) was added (toluene-4-sulfonylamino)-acetic acid methyl ester (15.65 g, 64.3 mmol), K2CO3 (17.78 g, 128.6 mmol) and then NaI (964 mg, 6.43 mmol). The resulting mixture was stirred at 50° C. overnight. After cooled, reaction mixture was partitioned between EtOAc and water. The organic layer was washed with water (2×) and brine. It was dried over Na2SO4, filtered and concentrated. Crude residue was purified by silica gel chromatography to provide the title compound (14.34 g, 29.8 mmol). 1H NMR in CDCl3, δ in ppm: 7.86 (d, 1H, 8.8 Hz), 7.70 (d, 2H, J=8.4 Hz), 7.38-6.8 (m, 9H), 4.88 (s, 2H), 3.99 (s, 2H), 3.82 (s, 3H), 3.53 (s, 3H), 2.41 (s, 3H).
