실험 절차

The mixture of 2-(4-fluorobenzylamino)benzoic acid (Step A, 0.7 g, 1.20 mmol), 7-amino-4,4-dimethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (0.71 g, 2.57 mmol), TBTU (0.917 g, 2.86 mmol), and DIEA (0.5 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, and brine, dried with MgSO4, filtered, and condensed. The residue was purified by flash column chromatography (0 to 30% of EtOAc in CH2Cl2), and the titled compound was obtained as oil. MS (ES+): 504 (M+H)+. Calc'd for C30H34FN3O3-503.26.
