Reaction Steps

Triethylamine (0.022 mL, 0.16 mmol) was added to N2-(4-(oxazol-5-yl)phenyl)-N4-phenyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (0.06 g, 0.16 mmol, Example 3) in DMF (1 mL) and dioxane (1 mL). Iodomethane (0.031 g, 0.22 mmol) was added and the reaction stirred at 25° C. for 1 h. Solvent was removed under reduced pressure and the crude product redissolved in DMSO. The crude product was purified by preparative HPLC to give 6-methyl-N2-(4-(oxazol-5-yl)phenyl)-N4-phenyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (0.014 g, 23%).
