59% | With copper(l) iodide; (R,R)-N,N'-dimethyl-1,2-diaminocyclohexane; caesium carbonate; In N,N-dimethyl-formamide; at 100℃; for 2h; | A solution of <strong>[57090-88-7]4-cyano-1H-imidazole</strong> (1000 mg, 10.74 mmol), 4-iodo -2-(trifluoromethyl)pyridine (3800 mg,14 mmol), (1R,2R)-N1,N2-dimethyl cyclohexane -1,2-diamine (150 mg, 1.07 mmol), CuI (200 mg, 1.07 mmol) and Cs2CO3 (7000 mg, 21.5 mmol) in 20 mL anhydrous DMF was stirred at 100 oC for 2 hours. The reaction mixture was cooled to room temperature and poured into 200 mL water. The mixture was extracted with ethyl acetate (80 mL*3). The organic layer were combined, washed by brine, dried by Na2SO4 and evaporated. The crude product was purified by silica flash column to afford compound 2 as white solid(1.5 g, 59percent yield). 1H-NMR(DMSO, 400 MHz)8.25 (d, 1H), 7.72 (d, 1H), 7.46 (s, 1H), 7.28 (s, 1H), 7.15 (s, 1H).
