Reaction Steps
To a solution of ethyl 3-methoxy-4-[2-(4-aminobenzyl)-4-thiazolyl]methoxybenzoate (87.8 mg, 0.220 mmol) in THF (2.0 mL) was added triethylamine (30.5 ul, 0.220 mmol) and o-tolyl isocyanate (30 μl), and the reaction mixture was stirred at room temp for 21 hr. The reaction mixture was poured into ice-water and the resulting precipitates filtered off. The filtrate was extracted with CHCl3, washed with H2O, and brine. The extract was dried over Na2SO4. The solvent was removed under a reduced pressure to afford 110.4 mg (94%) ethyl 3-methoxy4-[2-[4-[N′-(2-methylphenyl) ureido]benzyl]-4-thiazolyl]methoxybenzoate as a pale yellow crystalline powder. 1H-NMR (400 MHz, CDCl3) δ 1.38 (t, J=7.3 Hz, 3H), 2.28 (s, 3H), 3.92 (s, 3H), 4.28 (s, 2H), 4.35 (q, J=7.3 Hz, 2H), 5.29 (s, 2H), 6.20 (s, 1H), 6.47 (s, 1H), 6.97 (d, J=8.8 Hz, 1H), 7.20 (s, 1H), 7.24 (s, 2H), 7.27 (s, 2H), 7.33 (d, J=8.3 Hz, 2H), 7.49 (d, J=7.3 Hz, 1H), 7.56 (d, J=2.0 Hz, 1H), 7.63 (dd, J=2.0, 8.3 Hz, 1H); MS (FAB) m/z 532 (M++1).
