A solution of 1-{4-chloro-6-[(1E)-3,3-diethyltriaz-1-en-1-yl]-5-ethynyl-3′-fluorobiphenyl-2-yl}ethanol (2.3 g, 6.1 mmol) in 1,2-dichlorobenzene (59 mL) was heated in the microwave at 200° C. for 15 minutes. The reaction mixture was concentrated to give a black residue. Purification by flash column chromatography using acetonitrile in dichloromethane (0%-30%) gave the desired product (1.4 g, 74% for 2 steps). LCMS for C16H13ClFN2O (M+H)+: m/z=303.1; Found: 302.9.
