実験手順

To a stirred solution of (S)-8-chloro-3-(1-(1,3-dioxoisoindolin-2-yl)ethyl)-quinoline-2-carboxylic acid (100 mg, 0.26 mmol) in DMF (3.0 mL) was added sodium bicarbonate (66 mg, 0.79 mmol), hoat (54 mg, 0/39 mmol), acetic hydrazide (23 mg, 0.31 mmol) and edc (76 mg, 0.39 mmol). The reaction was stirred at r.t. for 2 hours and then it was diluted with ethyl acetate (60 mL) and water (20 mL). The separated aqueous layer was extracted with ethyl acetate (30 mL) and the combined organic layers were washed with LiCl (1.0 M aqueous solution, 30 mL), brine (30 mL) and then dried (MgSO4), filtered and evaporated in vacuo to give (S)—N′-acetyl-8-chloro-3-(1-(1,3-dioxoisoindolin-2-yl)ethyl)-quinoline-2-carbohydrazide. 1H NMR (400 MHz, CDCl3) δ ppm 10.45 (1H, s), 8.88 (1H, s), 8.64 (1H, s), 7.70-7.84 (4H, m), 7.64-7.66 (2H, m), 7.52 (1H, dd, J=5.3, 2.9 Hz), 6.87 (1H, q, J=7.0 Hz), 2.13 (3H, s), 1.98 (3H, d, J=7.0 Hz). Mass Spectrum (ESI) m/e=437.0 (M+1).
