실험 절차

To a stirred solution of 1-(2-aminophenyl)-N-[2-(2-hydroxyethoxy)ethyl]-methanesulfonamide (100 mg, 0.37 mmol), 1,3-dichloro-2-bromobenzene (103 mg, 0.46 mmol), K2CO3 (126 mg, 0.99 mmol) and XantPhos (21 mg, 0.04 mmol) in 1,4-dioxane (2 ml) under nitrogen in a microwave tube was added Pd2dba3 (17 mg, 0.019 mmol) in one portion and the tube sealed. The reaction was heated with stirring in a microwave at 160° C. for 30 minutes. The reaction was cooled before filtering through celite. The crude reaction mixture was purified by column chromatography eluting with ethyl acetate:hexane to afford 1-[2-(2,6-Dichlorophenylamino)phenyl]-N-[2-(2-hydroxyethoxy)-ethyl]methanesulfonamide as product (50.5 mg, 33%); Rf (ethyl acetate:hexane 1:1) 0.11; δH (400 MHz, CDCl3) 7.34 (3H, m), 7.23 (1H, t), 7.19 (1H, s), 7.02 (2H, m), 6.60 (1H, d), 5.70 (1H, s), 4.56 (2H, s), 3.70 (2H, s), 3.56 (4H, m), 3.29 (2H, dt) and 2.83 (1H, s); LCMS Rt=3.97 min, m/z (ES+) 441 (M+Na).
