YieldReaction ConditionsOperation in experiment
2.07 g With potassium carbonate; In N,N-dimethyl-formamide; at 90℃; for 3h; (2) Ethyl 2-bromo-4-trifluoromethyl- 1H-imidazole-5-car- boxylate (1.57 g, 5.47 mmol) was dissolved in DMF (11 mE), potassium carbonate (1.51 g, 10.9 mmol) and 2,5-dichlo- robenzyl bromide (1.58 g, 6.56 mmol) were added thereto, and the mixture was stirred at 90 C. for 3 hours. After the reaction, water (50 mE) was added and the mixture was extracted twice with ethyl acetate (50 mE). After being washed with saturated aqueous sodium chloride, the organic layer was dried over sodium sulfate. After concentrating the organic layer, the residue was purified by colunm chromatography to obtain ethyl 2-bromo- 1 -(2,5-dichlorobenzyl)-4-trif- luoromethyl-1 H-imidazole-5-carboxylate (2.07 g):10171] ?H-NMR (CDC13) oe: 7.38 (1H, d, J=8.3 Hz), 7.26-7.23 (1H, m), 6.43 (1H, d, J=2.4 Hz), 5.66 (2H, s), 4.32 (2H,q, J=7.1 Hz), 1.32 (3H, t, J=7.1 Hz);10172] ESI-MS mlz=445 (M+H).
