Reaction Steps

A mixture composed of 4-amino-N-(2-chloroethyl)-2-[(4-methoxy-3,5-dimethylpyridin-2-yl)methyl]-7,8-dihydro-2H-6-thia-1,2,3,5-tetraazaacenaphthylene-7-carboxamide of Example 16 (20 mg), isobutylamine (0.8 mL) and dioxane (3 mL) was heated under reflux for 16 hours, and then the reaction mixture was concentrated under reduced pressure. The resulting residue was purified by reversed phase liquid chromatography to obtain the title compound (6 mg, 28%) as a solid.
