508 mg (4.1 mmol) 3-fluorobenzylamine, 1.4 g (3.7 mmol) HATU and 1.5 ml (10.7 mmol) NEt3 were added consecutively to a solution of 1.0 g (3.7 mmol) 2-hydroxy-4-methyl-7-(trifluoromethyl)quinoline-3-carboxylic acid (synthesis see Example 4 Section a)) in THF (28 ml) and the solution was then stirred for 16 h at 50° C. The solution was subsequently diluted with EtOAc (30 ml). The resultant precipitate was filtered off and suspended in a EtOAc/MeOH/DCM mixture. Concentration in a vacuum was subsequently carried out. 1.0 g (2.6 mmol, 71%) N-(3-fluorobenzyl)-2-hydroxy-4-methyl-7-(trifluoromethyl)quinoline-3-carboxylic acid amide was obtained as a residue. The raw product was further converted without additional purification.
