실험 절차

A mixture of [3-({4-[(E)-2-(4-fluorophenyl)vinyl]phenyl}sulfonyl)phenyl]amine hydrochloride (Example 212, 100 mg, 0.26 mmol) and triethylamine (0.05 mL, 0.36 mmol) in tetrahydrofuran (2 mL) was cooled to 0° C. and ethyl isocyanate (0.08 mL, 0.31 mmol) added. The reaction was allowed to warm to room temperature and stirred for 3 hours. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over MgSO4 and evaporated. The residue was purified by flash column chromatography on silica, eluting with 40% ethyl acetate/isohexane, followed by trituration with diethyl ether to give the title compound as a white solid (27 mg, 24%). δH (500 MHz, d6 DMSO): 8.85 (1H, s), 8.15 (1H, s), 7.86 (2H, d, J=8.4 Hz), 7.79 (2H, d, J=8.4 Hz), 7.67 (2H, dd, J=5.7, 8.5 Hz), 7.50-7.48 (1H, m), 7.43-7.40 (3H, m), 7.27 (1H, d, J=16.5 Hz), 7.22 (2H, t, J=8.8 Hz), 6.20 (1H, t, J=5.4 Hz), 3.12-3.06 (2H, m), 1.03 (3H, t, J=7.1 Hz).
