실험 절차

A stirred solution of ethyl 2-(4-amino-1-methylpiperidin-4-yl)acetate (53 mg, 0.263 mmol) in CH2Cl2 (2 mL) was treated with NEt3 (0.11 mL, 0.789 mmol), and 2,5-dioxopyrrolidin-1-yl 5-(phenylethynyl)furan-2-carboxylate, prepared as described in Preparation 5 (89 mg, 0.289 mmol). The reaction was stirred overnight, at room temperature, then the solvent removed in vacuo and the product purified by column chromatography to obtain the title compound (51 mg, 49%). 1H NMR (400 MHz, CD3OD) δ 7.57-7.53 (m, 2H), 7.44-7.40 (m, 3H), 7.16 (s, 1H), 6.84 (s, 1H), 4.08 (q, 2H, J=7.2 Hz), 2.89 (s, 2H), 2.70-2.65 (m, 2H), 2.54-2.47 (m, 2H), 2.39-2.25 (m, 5H), 1.85-1.80 (m, 2H), 1.17 (t, 3H, J=7.2 Hz); MS ESI 395.2 [M+H]+, calcd for [C23H26N2O4+H]+ 395.47.
