Reaction Steps

67 mg (0.17 mmol) 4-(7-methoxy-2-oxo-1,2,4,5-tetrahydro-benzo[d][1,3]diazepin-3-yl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4′-carboxylic acid and 30 mg (0.17 mmol) 1,2,2a,5-tetrahydro-3H-pyrrolo[4,3,2-de]quinolin-4-one in 56 μL (0.40 mmol) TEA and 1.8 mL DMF were combined with 58 mg (0.18 mmol) TBTU and stirred overnight at RT. Then the reaction mixture was purified by preparative HPLC-MS. The product-containing fractions were combined and freeze-dried.
