87 μl (0.8 mmol) 4-fluorobenzylamine, 266 mg (0.7 mmol) HATU and 281 μl (2.0 mmol) NEt3 were added consecutively to a solution of 199 mg (0.7 mmol) 2-methoxy-4-methyl-7-(trifluoromethyl)quinoline-3-carboxylic acid in THF (5 ml) and the solution was then stirred for 72 h at RT. The solution was subsequently diluted with EtOAc and washed with a 4N aq. NH4Cl sol., a 1M aq. Na2CO3 sol. and brine. The organic phase was dried over MgSO4, filtered through silica gel and concentrated in a vacuum. After crystallisation (EtOAc/hexane 1:2) of the residue, 161 mg (0.4 mmol, 59%) N-[(4-fluorophenyl)-methyl]-2-methoxy-4-methyl-7-(trifluoromethyl)-quinoline-3-carboxylic acid amide (example 5) was obtained. MS: m/z 393.1 [M+H]+.
