Short-RInChIKey=SA-FUHFF-UHFFFADPSC-ZACAHENACG-UHFFFADPSC-NUHFF-NJTWA-NUHFF-ZZZ
5-[(~{E})-(Diisopropylamino)azo]-1~{H}-pyrazole-4-carbonitrile (77.8 mg, 353 μmol, 1.00 equiv) was dissolved in DMSO (3.0 mL) and cesium carbonate (138 mg, 424 μmol, 1.20 equiv) was added. The reaction mixture was cooled to 0 °C and methyl 4-(bromomethyl)benzoate (162 mg, 706 μmol, 2.00 equiv) was slowly added. After the addition, the reaction mixture was slowly warmed to 21 °C and stirred for 2 days at this temperature. For work up, ice-water was added to the reaction mixture. The aqueous phase was extracted three times with ethyl acetate and the combined organic phase was washed with water and brine, dried over Na2SO4 and filtered
