Reaction Steps

100 mg (0.36 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one, 90 mg (0.34 mmol) 6-(6-chloropyrimidin-4-yloxy)benzo[d]oxazol-2(3H)-one and 0.07 mL (0.41 mmol) DIPEA in 2.0 mL DMF were stirred overnight at RT and for 4 h at 40° C. The reaction mixture was purified by preparative HPLC-MS. The fractions containing product were partially evaporated down i.vac. The precipitate formed was suction filtered, washed and dried.
