Reaction Steps

44 mg (0.16 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one, 40 mg (0.13 mmol) 6-(6-chloropyrimidin-4-yloxy)-2-cyclopropyl-4-methyl-1H-benzo[d]imidazole and 0.06 mL (0.32 mmol) DIPEA in 2.0 mL DMF were stirred overnight at RT. The reaction mixture was purified by preparative HPLC-MS. The fractions containing the product were partially evaporated down i.vac. and neutralised with 4M sodium hydroxide solution. The precipitate formed was suction filtered, washed and dried.
