Reaction Steps

100 mg (0.25 mmol) of 6-[4-(7-methoxy-2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidin-1-yl]-pyrimidine-4-carboxylic acid and 50 mg (0.32 mmol) (2,3-dihydro-1H-indol-3-yl)-methanol in 50 μL (0.27 mmol) TEA and 0.90 mL DMF were combined with 85 mg (0.27 mmol) TBTU and the mixture was stirred for 5 h at RT. Then the reaction mixture was purified by preparative HPLC-MS. The product-containing fractions were combined and evaporated down by roughly half. The precipitated solid was suction filtered and dried.
