참여 물질

반응 단계

2,5-Dichlorophenol (17.86 g, 109.54 mmol) and 4-chloro-3-nitrobenzonitrile (10.00 g, 54.77 mmol) were combined with K2CO3 (37.85 g, 273.85 mmol) in THF (300 mL). The reaction mixture was refluxed for 48 hrs and then the solid was filtered over a bed of Celite. After rinsing the residue with copious amounts of DCM, the filtrate was concentrated to produce a yellow solid. The solid was triturated with minimal DCM and collected via vacuum filtration to yield compound 34 (13.84 g, 81.7% yield, 100.0% pure). 1H NMR (500 MHz, DMSO-d6): δ 8.73 (s, 1H), 8.12 (dd, J1=9 Hz, J2=2 Hz, 1H), 7.73 (d, J=9 Hz, 1H), 7.65 (d, J=2 Hz, 1H), 7.48 (dd, J1=9 Hz, J2=2 Hz, 1H), 7.21 (d, J=9 Hz, 1H).
