Reaction Steps
To a stirring mixture of 4-chloromethyl-N-[4-methyl-3-(2-pyridin-4-yl-6-(trifluoromethyl)pyrimidin-4-ylamino)-phenyl]benzamide (48 mg, 0.096 mmol) and 1-methylpiperazine (16 pl, 0.0.144 mmol) in anhydrous tetrahydrofuran (5 ml) was added N,N-diisopropylethylamine (200 μl). The mixture was refluxed for 20 h. The mixture was cooled to room temperature and then rotary evaporated to dryness. The residue was purified by column chromatography and isolated as a tan solid (22 mg, 41%). 1H NMR (CDCl3): 8.77 (dd, J=1.8, 4.5 Hz, 2H), 8.29 (dd, J=1.5, 4.5 Hz, 2H), 8.01 (s, 1H), 7.85 (s, 1H), 7.83 (d, J=8.1 Hz, 2H), 7.47 (d, J=1.8 Hz, 2H), 7.37 (dd, J=1.5, 8.4 Hz, 1H), 7.33 (d, J=8.4 Hz, 1H), 7.04 (s, 1H), 6.74 (s, 1H), 3.57 (s, 2H), 2.47 (s, 8H), 2.29 (s, 6H).
