Reaction Steps

7-(Bromomethyl)-4-(4-fluorophenyl)quinoline-2-carbonitrile (2-1, 100.0 mg, 0.293 mmol, 1.0 equiv.), DIEA (0.051 ml, 0.293 mmol, 1.0 equiv.), and 1-H-pyrazole-4-carbaldehyde (33.8 mg, 0.352 mmol, 1.2 equiv.) were added to acetonitrile (1.0 mL) in a microwave reaction vessel and the resulting mixture was irradiated with microwave at 180° C. for 30 minutes. The reaction mixture was cooled and concentrated and the residue was purified by reverse phase HPLC (H2O/CH3CN gradient w/0.1% TFA modifier) to afford 4-(4-fluorophenyl)-7-[(4-formyl-1H-pyrazol-1-yl)methyl]quinoline-2-carbonitrile (3-8, 55.0 mg, 52.7%) as a colorless solid. LRMS m/z (M+H)+ 357.1 found, 357.1 required.
