実験手順

To a 500 mL round-bottomed flask was added 5-chloro-4-(1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxylic acid (4.2 g, 17.31 mmol), 2-[(2S)-2-amino-3-(3-fluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (6.37 g, 19.04 mmol) [prepared according to the procedure of Preparation 6], N,N-diisopropyl ethylamine (4.53 ml, 26.0 mmol) and Pybrop (12.05 g, 26.0 mmol) in dichloromethane (DCM) (150 ml). After stirring at RT for 12 h, the reaction solution was washed with H2O (2×100 mL) and the organic layer was dried Na2SO4, filtered and concentrated. The crude product was added to a silica gel column and was eluted with [EtOAc/hexanes, 1:1] to give the product [7.8 g, 86%] as a white solid: LCMS (ES) m/z 524 (M+H)+.
