Versuchsvorschrift

30 mg of 4-(4-fluoro-6-hydroxyquinolin-2-yl)benzoic acid (Compound 26) was mixed with 1 mmol Me2NH.HCl and 0.5 ml DIEA in 3 ml DMF and heated to 160° C. for 30 minutes. The solvent was evaporated to dryness and water was added. The solid was filtered and washed with water and dried. The crude was triturated with acetone to obtain 10.5 mg of Compound 47. 1H NMR (DMSO-d6 300 MHz TMS): δ 13.2 (b, 1H), 10.28 (s, 1H), 8.22 (m, 2H), 8.11 (d, 1H), 7.99 (d, 1H), 7.50 (s, 1H), 7.39 (d, 1H), 7.26 (s, 1H), 3.24 (s, 6H), MS (ESI): m/z=309.30 [M+1]+.
