Versuchsvorschrift

To a solution of 3,4-dihydro-1H-isoquinoline-2,5-dicarboxylic acid 2-tert-butyl ester (2 g, 7.2 mmol), 2-amino-indan-2-carboxylic acid ethyl ester (1.5 g, 7.2 mmol), HATU (3.27 g, 8.6 mmol) in anhydrous DMF (20 mL) is added DIPEA (1.42 mL, 8.6 mmol). The resulting solution is stirred at RT overnight. After the removal of DMF in vacuo, the residue is dissolved in EtOAc (150 mL) and washed with water (1×20 mL) and brine (2×20 mL). The organic layer is dried over anhydrous Na2SO4 and concentrated in vacuo. The residue is purified by HPLC to give a pure product (71) as white solid (1.02 g, 30%).
