Methylamine was bubbled through a mixture of N-(6-methoxypyridin-3-yl)-3-(4-methyl-6-(methylthio)-1,3,5-triazin-2-yl)-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-2-amine (33 mg, 0.064 mmol) in IPA (1.50 mL, 19.47 mmol) for 15 min and then allowed to stand overnight. The resulting precipitate was collected by filtration and washed with a minimal amount of IPA to give 4-(2-(6-methoxypyridin-3-ylamino)-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)pyridin-3-yl)-N,6-dimethyl-1,3,5-triazin-2-amine (17.1 mg, 1.761 mmol, 54.7% yield) as a yellow solid. 1H NMR (400 MHz, d6-DMSO) mixture of rotamers δ 11.26-12.03 (m, 1H); 8.73 (d, J=13.69 Hz, 1H); 8.38-8.63 (m, 1H); 7.96-8.38 (m, 3H); 6.83 (d, J=8.41 Hz, 1H); 3.84 (br. s., 3H); 3.50 (d, J=12.72 Hz, 2H); 3.11 (br. s., 4H); 2.90-3.03 (m, 3H); 2.86 (br. s., 3H); 2.47-2.50 (m, 4H); 2.44 (br. s., 3H). m/z (ESI, +ve ion) 500.1 (M+H)+.
