Reaction Steps

80 mg (0.20 mmol) 6-[4-(7-methoxy-2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidin-1-yl]pyrimidine-4-carboxylic acid and 30 mg (0.20 mmol) 6-methoxy-2,3-dihydro-1H-indole in 50 μL (0.36 mmol) TEA and 1.5 mL DMF were combined with 70 mg (0.22 mmol) TBTU and the mixture was stirred for 1 h at RT. Then the reaction mixture was purified by preparative HPLC-MS. The product-containing fractions were combined and freeze-dried.
