YieldReaction ConditionsOperation in experiment
85% With bromine; acetic acid; at 20℃; for 48h;Inert atmosphere; To a suspension of 7-(trifluoromethyndone23dione (0.5 g, 2.3 rnmo) in AcOH (2.3 mL) was added bromine (0.14 mL, 2.79 mmo). The mixture was sHowed to stir at rt and after 24 h an additiona 100 iL of bromine was added. The reaction was stirred at rt for an additiona? 24 h, then poured nto ice and stirred for 0.5 h. The resufting mixture was fHtered and the sohds were washed with H20 to afford the title compound as an orange sohd (585 mg, 85percent). NMR(400 MHz, DMSO-d6) oe 11.58 (s, I H), 8.07 7,99 (m, I H), 7.99 7.91 (m, I H).
82% With bromine; In acetic acid; at 20℃; Intermediate 6 (4.56 g, 21.2 mmol) was taken up in 45 mL of acetic acid in a 250 mL round-bottom flask, and bromine (5.4 mL, 17 g, 0.11 mol) was added. The solution was stirred overnight at room temperature. LC-MS analysis showed that complete conversion to product had not occurred. Additional bromine was added (1.1 mL, 3.4 g, 21 mmol) and the resulting mixture was stirred for additional 5 hours. The reaction mixture was poured onto crushed ice and allowed to stand until the ice had melted. The precipitate was collected by filtration, washed repeatedly with water, and dried under vacuum to give fine, bright orange crystals (intermediate 93, 5.12 g, 82percent yield). 1H NMR (400 MHz, DMSO-d6) delta 7.96 (d, J=2.0 Hz, 1H), 8.04 (d, J=2.0 Hz, 1H), 11.59 (s, 1H).
