Reaction Steps

83 mg (0.21 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 37 mg (0.24 mmol) 5,6,7,8-tetrahydro-4H-thiazolo[4,5-d]azepine in 0.13 mL (0.72 mmol) DIPEA and 1.0 mL DMF were combined with 77 mg (0.24 mmol) TBTU and the mixture was stirred overnight at RT. Then the reaction mixture was purified by preparative HPLC-MS. The product-containing fractions were combined and freeze-dried.
