YieldReaction ConditionsOperation in experiment
62% With potassium hydroxide; In tert-butyl alcohol; at 70℃; D. 4.5-Difluoro-1 H-indoleA mixture of (3,4-difluoro-2-trimethylsilanylethynyl-phenyl)-carbannic acid ethyl ester (220 mg, 0.7407 mmol) and KOH (332 mg, 5.927 mmol) in f-BuOH (10 ml_) is heated at 70 0C overnight. The solvent is removed in vacuo, and the residue is partitioned between H2O and Et2O. The two layers are separated, and the organic layer is washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. The crude material is purified on silica gel with heptane/EtOAc (100/0 to 50/50) as eluant 71 mg (62%) of the product as a clear brown solid. 1H NMR (CDCI3): delta 8.20 (br, s, 1 H), 7.30-7.15 (m, 1 H), 7.10-6.95 (m, 2H), 6.70-6.60 (m, 1 H); 19 F NMR (CDCI3):delta -147.78 (m, 1 F), -155.94 (m, 1 F).
