Reaction Conditions

Reaction Steps

To a mixture of 7-chloro-4-(3-furyl)quinoline (30.2 g) and NiCl2 (dppp) (7.1 g) in Et2O (950 mL) was added MeMgBr (141 mL of a 1.4M solution in 3:1 THF:toluene) at such a rate to maintain a temperature of 30° C. The mixture was refluxed for 30 min., cooled to 0° C. and saturated NH4Cl (200 mL) was added followed by H2O (100 mL). The layers were separated and the aqueous phase was extracted with EtOAc. The combined organics were washed with NH4OAc buffer, brine, dried (MgSO4) and concentrated. Chromatography (silica gel; EtOAc/hexane (3:7)) provided the title compound as a beige oil.
