Reaction Steps

64 mg (0.23 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one, 64 mg (0.23 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 40 mg (0.15 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-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.
