実験手順

N,N-diisopropylethylamine (5.3 mL, 30.6 mmol) was added dropwise to a mixture of pyrrolidine-1,3-dicarboxylic acid 1-tert-butyl ester (2.2 g, 10.1 mmol), HATU (4.0 g, 10.5 mmol), the HCl salt of 2-amino-1-(4-bromophenyl)ethanone (2.4 g, 9.6 mmol), and DMF (40 mL), and stirred at ambient condition for 1 hour. Most of the volatile component was removed in vacuo, and the resulting residue was dissolved in ethyl acetate (150 mL), washed with water and brine, dried over Na2SO4, filtered and concentrated in vacuo. The obtained residue was purified by flash chromatography to provide the desired product as a white foam-like solid (3.5 g, 90%). m/z 432.9, 434.9 (M+Na)+.
