A solution of 5-bromo-8-quinolinecarboxaldehyde (987 mL, 418 mmol), 5-hexyn-1-yl-benzene [CAS 100848-88-2] (1.05 mL, 5.85 mmol), triethylamine (2 mL) and 1,3-bis(diphenylphosphino)propane (dppp, 59 mg) in DMF (10 mL) was heated to 90° C. with stirring for 2 h. After cooling to RT, the reaction mixture was extracted with ether and washed with water and brine, dried over magnesium sulfate and concentrated. Purification by MPLC (35% ethyl acetate in hexanes) gave rise to 1.04 g of Intermediate.
