Procedure

A mixture of 2-[(1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-amino]-benzoic acid (Step A, 516 mg, 2.0 mmol), 7-amino-4,4-dimethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (552 mg, 2.0 mmol), TBTU (0.706 g, 2.2 mmol), and DIEA (0.7 mL) in 30 mL of CH2Cl2 was stirred at RT for 2 h, then diluted with more CH2Cl2. The organic layer was washed with water, brine, dried with MgSO4, filtered, and condensed. The residue was purified by flash column chromatography (0 to 30% of EtOAc in CH2Cl2), to obtain the titled compound as oil. MS (ES+): 526 (M+H)+. Calc'd for C31H35N5O3-525.27.
