Versuchsvorschrift

A glass microwave reaction vessel was charged with N2-cyclopentyl-N4-(6-methoxypyridin-3-yl)-5-(4-methyl-6-(methylthio)-1,3,5-triazin-2-yl)pyrimidine-2,4-diamine (36 mg, 0.085 mmol), ammonia (0.5 mL, 23.11 mmol) and dioxane (2 mL). The reaction mixture was stirred and heated in an oil bath at 100° C. for 24 h. The solvent was removed in vacuo and the residue was purified by silica gel chromatography eluting with EtOAc to give 5-(4-amino-6-methyl-1,3,5-triazin-2-yl)-N2-cyclopentyl-N4-(6-methoxypyridin-3-yl)pyrimidine-2,4-diamine (28 mg, 0.071 mmol, 84% yield). 1H NMR (300 MHz, CDCl3) δ 11.99 (s, 1H); 9.21 (s, 1H); 8.29-8.56 (m, 1H); 8.19 (s, 1H); 6.76 (d, J=8.92 Hz, 1H); 5.26 (s, 3H); 4.25 (s, 1H); 3.95 (s, 3H); 2.49 (s, 3H); 2.04 (s, 2H); 1.34-1.87 (m, 6H). m/z (ESI, +ve ion) 394.1 (M+H)+.
