実験手順
To a solution of 1,1-dimethylethyl [(1S,2E)-4-(2,3-dihydro-1H-indol-1-yl)-1-(2-methylpropyl)-4-oxo-2-buten-1-yl]carbamate (3.21 g, 8.95 mmol) in CH2Cl2 (10.0 mL) was added TFA (10 mL, 130 mmol). The reaction mixture was stirred for 17.5 h at RT and then concentrated under reduced pressure and dried under high vacuum to afford the title compound. LC-MS m/z 259 (M+H)+, 0.76 min (ret time).
