実験手順

1,4-dioxane (0.1 mL, 1.169 mmol) and 2 N HCl (0.219 mL, 0.437 mmol) was added to a mixture of 4-(2-chloro-5-methoxypyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (110 mg, 0.437 mmol) and 5-amino-2-methoxypyridine (Aldrich, St. Louis, Mo.) (81 mg, 0.656 mmol) in a microwave reaction vessel and the mixture was sealed and heated at 140° C. for 60 min in a Personal Chemistry microwave unit under microwave irradiation. After cooling, the resulting dark mixture was concentrated. Flash column chromatographic purification (short column, SiO2, pure DCM to 5% MeOH in DCM) provided the title compound mixed with starting material. This was washed with methanol several times and finally the solid was recrystallized from MeOH to give 4-(5-methoxy-2-(6-methoxypyridin-3-ylamino)pyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (21 mg, 0.062 mmol, 14.16% yield) as a yellow-green powder.
