Procedure

70.0 mg (0.19 mmol) 3-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidin-1-yl]-benzoic acid, 60 mg (0.27 mmol) 7,7-dimethyl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine-dihydrochloride, 100 μL (0.71 mmol) triethylamine and 70.0 mg (0.22 mmol) TBTU in 1 mL DMF were stirred overnight at RT. The reaction mixture was combined with 1 mL methanol and 10 mL ice water. The precipitated product was suction filtered, washed with water and diethyl ether and purified by preparative HPLC. The product fractions were combined and evaporated down i. vac.
