To a flask containing a magnetic stir bar was added 0.03 g (0.20 mmol) of 3-methyl-1H-indazol-6-amine and 0.060 g (0.20 mmol) of 4-chloro-N-{3-[(methylsulfonyl)methyl]phenyl}-1,3,5-triazin-2-amine and 2 mL of isopropanol and the resultant mixture was heated at reflux for ca. 16 hours. Upon cooling the reaction mixture a solid precipitated. The solid was filtered and washed with ethyl acetate (2×4 mL), acetonitrile (4 mL), and ethyl ether (4 mL) and dried under vacuum to give N2-(3-methyl-1H-indazol-6-yl)-N4-{3-[(methylsulfonyl)methyl]phenyl}-1,3,5-triazine-2,4-diamine hydrochloride as a solid. The solid was purified by C-18 RP-HPLC using an acetonitrile/water gradient containing 0.5% trifluoroacetic acid buffer. Concentrating the proper fractions gave 0.015 g (10%) of N2-(3-methyl-1H-indazol-6-yl)-N4-{3-[(methylsulfonyl)methyl]phenyl}-1,3,5-triazine-2,4-diamine trifluoroacetate as a white solid. HNMR: δ12.4 (br s, 1H), 9.9 (br s, 1H), 8.34 (s, 1H), 7.8 (br s, 1H), 7.67 (br s, 1H), 7.56 (d, 1H), 7.29(m, 2H), 7.02 (d, 1H), 4.34 (br s, 2H), 2.83 (br s, 3H), 2.40 (s, 3H). MS (ES+, m/z)=409 (M+H).
