実験手順

7-[(Tert-butoxycarbonyl)amino]-2-methyl-1-oxo-2,3-dihydro-1H-isoindole-4-carboxylic acid (Compound 116C, 45 mg, 0.15 mmol), pyrrolidine (123 uL, 1.47 mmol), TBTU (236 mg, 0.734 mmol), DIPEA (128 uL, 0.734 mmol) and DMF (1 mL) were mixed and stirred at room temperature for 2 hours. The reaction mixture was diluted with EtOAc and washed with water (2×) and brine. The crude product was purified by column chromatography. MS (ES+): m/z 360.34 (100) [MH+]; HPLC: tR=1.20 min (UPLC, Analytical).
