実験手順

A mixture of 7-amino-4,4-dimethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (4.0 g, 14.60 mmol), 2-amino-benzoic acid (2.0 g, 14.60 mmol), TBTU (5.2 g, 16.06 mmol) and DIEA (2.7 mL, 16.06 mmol) in DMF (5 mL) was heated (50° C.) for 12 h in a sealed tube. The mixture was diluted with EtOAc and water. The aqueous layer extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. The crude material was purified by flash chromatography (SiO2, 20% EtOAc/hexane) to afford a pinkish solid. MS (ES+): 396.0 (M+H)+. Calc'd for C23H29N3O3-395.49.
