Reaction Steps

5-(2-Methoxyethylamino)-3-methyl-7-(2-methylbenzo[d]oxazol-6-yl)pyrido[4,3-d]pyrimidin-4(3H)-one was synthesized, as described in Example 9, from 6-bromo-2-methylbenzo[d]oxazole and 7-chloro-5-(2-methoxyethylamino)-3-methylpyrido[4,3-d]pyrimidin-4(3H)-one. After purification by preparatory LC/MS, it was partially decomposed to N-(2-hydroxy-4-(5-(2-methoxyethylamino)-3-methyl-4-oxo-3,4-dihydropyrido[4,3-d]pyrimidin-7-yl)phenyl)acetamide. The two compounds are separated again by preparatory TLC.
