Reaktionsschritte

The mixture of rac-3-bromo-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one (100 mg, 0.270 mmol), 1-(4-trifluoromethyl-phenyl)-piperazine (75 mg, 0.324 mmol) and DIPEA (42 mg, 0.324 mmol) In acetonitrile (3 mL) was stirred at room temperature for overnight. The crude was concentrated and the residue was purified with preparative HPLC to give 76 mg of rac-6-chloro-3-(3-chloro-benzyl)-3-[4-(4-trifluoromethyl-phenyl)-piperazin-1-yl]-1,3-dihydro-indol-2-one as a white solid. MS: 520 (M+H)+. H1-NMR (400 MHz, CDCl3) δ 7.584 (s, 1H), 7.493 (d, 2H), 7.240 (d, 1H), 7.081 (t, 2H), 7.011 (t, 1H), 6.908 (d, 3H), 6.766 (d, 1H), 6.684 (d, 1H), 3.431 (d, 1H), 3.329-3.206 (m, 5H), 2.947 (t, 4H).
