O-(Benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium tetrafluoroborate → 3-{-[6-(5-hydroxymethyl-4.7-dihydro-5H-thieno[2,3-c]pyridin-6-carbonyl)-pyrimidin-4-yl]-piperidin-4-yl}-7-methoxy-1,3,4,5-tetrahydro-benzo[d][1,3]diazepin-2-one

Reaction Steps

100 mg (0.25 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 50 mg (0.28 mmol) (4,5,6,7-tetrahydro-thieno[2,3-c]pyridin-5-yl)-methanol in 50 μL (0.36 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 roughly by half. The precipitate formed was suction filtered and dried.
