Reaction Steps

4-(1H-Pyrazol-3-yl)-benzonitrile (100 mg, 0.591 mmol), 1-(4-bromophenyl)-propan-1-one (126 mg, 0.591 mmol), Cs2CO3 (770 mg, 2.364 mmol), CuI (4 mg, 0.018 mmol), 8-hydroxyquinoline (3 mg, 0.018 mmol), and DMF/H2O (2 mL; 10:1 solution) were combined in a 10 mL CEM Microwave reaction vessel fitted with magnetic stir bar and subjected to microwave irradiation at 150° C. for 30 min. The contents were then filtered and concentrated to dryness affording the nitrile (158 mg, 0.508 mmol, 86%). Reduction of the nitrile to the corresponding aldehyde was accomplished following the DIBAL procedure described earlier.
