Procedure

Bromo[4-(ethyloxy)-4-oxobutyl]zinc (Aldrich; 0.5 M in THF, 2 ml) was added dropwise to a solution of 1-bromo-5-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)isoquinoline (D40; 0.15 g) and tetrakis(triphenylphosphine)palladium(0) (50 mg) in THF (5 ml). The resulting solution was heated to reflux for 1 hour. The solvent was evaporated in vacuo and the residue was dissolved in DCM (20 ml). The organic solution was washed with 0.5 M aq. NaOH (8 ml), then dried over anhydrous sodium sulphate. The dried solution was filtered and the filtrate was concentrated. The residue was purified by column chromatography to give the title compound (0.1 g).
