Reaction Steps

To a solution of methyl 4-[2-(methanesulfonyloxy)ethoxy]benzoate (2.74 g, 10 mmol) in MeCN (50 ml), was added aniline (9.1 ml, 100 mmol) at rt. The reaction was stirred for 64 hours at reflux. The mixture was poured into H2O (200 mL), extracted with EtOAc (100 mL×2), dried over MgSO4. After removal of the solvent in vacuo, the unreacted aniline was removed in vacuo by co-evaporation with toluene (10 mL×3) at 80° C. The residue was chromatographed on silica gel (middle pressure chromatography system: YAMAZEN YFLC-5404-FC, f50 mm×150 mm, CHCl3) to give methyl 4-[2-(N-phenylamino)ethoxy]benzoate (2.23 g, 82%) as a colorless oil. 1H-NMR (CDCl3) δ 3.56 (t, J=5.1 Hz, 2 H), 3.90 (s, 3 H), 4.21 (t, J=5.1 Hz, 2), 6.68 (dd, J=1.0 Hz, 8.6 Hz, 2 H), 6.75 (t, J=7.3 Hz, 1 H), 7.20 (AB type d, J=7.3 Hz, 2 H), 8.00 (d, J=9.1 Hz, 2 H); MS (ESI) m/z 272 (M++1).
