Diisopropylethylamine → 1-{1-[6-(4-Methyl-2-oxo-2,3-dihydro-benzoxazol-6-yloxy)-pyrimidin-4-yl]-piperidin-4-yl}-1,3-dihydro-imidazo[4,5-b]pyridin-2-one

Reaction Steps

40 mg (0.18 mmol) 1-piperidin-4-yl-1,3-dihydroimidazo[4,5-b]pyridin-2-one, 50 mg (0.18 mmol) 6-(6-chloro-pyrimidin-4-yloxy)-4-methyl-3H-benzoxazol-2-one and 0.10 mL (0.58 mmol) DIPEA were combined in 1.8 mL DMF and stirred for 1 h at RT. Then another 40 mg (0.18 mmol) 1-piperidin-4-yl-1,3-dihydroimidazo-[4,5-b]pyridin-2-one were added and the mixture was stirred overnight. The reaction mixture was purified by preparative HPLC-MS. The product-containing fractions were combined, the acetonitrile was evaporated down, the precipitate was suction filtered and dried i. vac.
