Reaction Steps

6-Acetyl-2-(4-(oxazol-5-yl)phenylamino)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4-yl trifluoromethanesulfonate (35 mg, 0.07 mmol, Example 26a) in DMSO (1 mL) was dispensed in a library plate. N-methyl-1-(pyridin-3-yl)methanamine (8.55 mg, 0.07 mmol) was added and it was left to shake overnight at 80° C. before filtered and purified by preparative HPLC to yield 1-(4-(Methyl(pyridin-3-ylmethyl)amino)-2-(4-(oxazol-5-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)ethanone (17 mg, 52%).
