Diisopropylethylamine → 3-{1-[6-(2,7-dimethyl-3H-benzimidazol-5-yloxy)-pyrimidin-4-yl]-piperidin-4-yl}-7-methoxy-1,3,4,5-tetrahydro-benzo[d][1,3]diazepin-2-one

Reaction Steps

0.16 g (0.59 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one, 0.15 g (0.55 mmol) 6-(6-chloro-pyrimidin-4-yloxy)-2,4-dimethyl-1H-benzimidazole and 0.21 mL (1.2 mmol) DIPEA were combined in 2.0 mL DMF and stirred overnight at RT. The reaction mixture was purified by preparative HPLC-MS. The product-containing fractions were combined and the acetonitrile was evaporated down. The residue was made alkaline with 4N aqueous sodium hydroxide solution, the precipitate formed was suction filtered, washed with water and dried under HV.
