Reaction Steps

3-{[6-Chloro-4-(2,2,2-trifluoro-ethylamino)-pyrido[3,2-d]pyrimidin-2-ylamino]-methyl}-benzenesulfonamide (0.077 g) was combined with 3-methylsulfonyl-phenylboronic acid (0.067 g), palladium tetrakistriphenylphosphine (0.006 g) and potassium carbonate (0.121 g). The mixture was suspended in DME (1.6 mL) and water (0.8 mL), sealed and heated by microwave to 120° C. for 3 min. Crude product was precipitated by the addition of water. The precipitate was filtered and purified by reverse phase HPLC (5-100% ACN/H2O+0.1% TFA) to give 0.048 g (41% yield) of the title compound, which was characterized by its NMR and mass spectrum as follows: 1H NMR (d6-DMSO): d 3.34 (s, 3H), 4.40-4.46 (m, 2H), 4.73-4.82 (m, 2H), 7.35 (s, 2H), 7.52-7.7.64 (m, 2H), 7.73-7.75 (m, 1H), 7.83-7.87 (m, 2H), 8.03-8.06 (m, 2H), 8.58-8.62 (m, 1H), 8.68 (s, 1H), 8.80 (d, 1H), 9.10 (bs, 1H), 9.98 (bs, 1H); MS (m/z): 567.1 ([M+H]+, 100).
