A mixture of [2-Chloro-6-(4-fluoro-phenyl)-pyrido[3,2-d]pyrimidin-4-yl]-(1-trifluoromethyl-cyclopropyl)-amine (51.6 mg) and 4-aminomethyl-benzenesulfonamide hydrochloride (51.4 mg) was dissolved in NMP (1 mL) and treated with diisopropylethylamine (0.065 mL). The reaction mixture was sealed and heated by microwave to 140° C. for 1.5 h. The reaction mixture was cooled and purified by preparative HPLC (5-95% acetonitrile:water with 0.1% TFA) to afford 36 mg (41% yield) of the title compound as its TFA which was characterized by its NMR and mass spectrum as follows: 1H NMR (d6-DMSO): d 1.26 (br s, 2H), 1.37 (br s, 2H), 4.80 (d, 2H), 7.34-7.40 (m, 4H), 7.55 (d, 2H), 7.78 (d, 2H), 7.99 (d, 1H), 8.48 (m, 3H), 8.9 (br s, 1H), 10.1 (br s, 1H); MS (m/z): 533.2 ([M+H]+, 100).
