YieldReaction ConditionsOperation in experiment
42% With N-Bromosuccinimide; In dichloromethane; at 20℃; for 0.416667h; Example 35: (5-Chloro-2-f(E)-3-f3-(4-fluoro-benzvl)-3,8-diaza-bicvdoo3.2.11oct-8-yll-3-oxo- propenvll-4-trifluoromethoxv-phenyl)-urea; a) 2-Bromo-5-chloro-4-trifluoromethoxy-phenylamine; N-Bromosuccinimid (7.9 g; 44.5 mmol) in CH2CI2 (500 ml) is added under stirring within 5 min. to a solution of <strong>[64628-73-5]3-chloro-4-trifluoromethoxy-phenylamine</strong> (9.4 g; 44.5 mmol) in CH2CI2 (100 ml) at room temp. After 20 min. the reaction mixture is concentrated to a volume of -150 ml, and hexanes (1000 ml) added to the precipitated crystals. The crystals are filtered off an purified via chromatography (Si02; TBME/hexanes 1/9 to 2/8) to deliver the target compound as yellowish crystals (8.4 g; 42 %). 1 H-NMR (400MHz; DMSO-d6), 8 (ppm) : 5.81 (s, 1 H); 6.94 (s, 1 H); 7.55 (s, 2H). MS (m/z) ES-: 290 (MH-).
