실험 절차

To a 0° C. suspension of NaH (16 mg, 0.6 mmol) in DMF (1 mL), (E)-2-(4-tert-butylphenyl)-N′-(isoquinolin-5-ylmethylene)cyclopropanecarbohydrazide (200 mg, 0.53 mmol) was added portionwise under nitrogen atmosphere. After being stirred for 1 h at 0° C., MeI (0.15 g, 1.0 mmol) was added and the reaction mixture stirred at RT for 1 h. The reaction mixture was then quenched with ice water and stirred for an additional 10 minutes. The precipitated solid was filtered and dried in vacuo to obtain the crude product. The crude material was purified via silica gel column chromatography using 20% ethyl acetate in hexanes to afford (E)-2-(4-tert-butylphenyl)-N′-(isoquinolin-5-ylmethylene)-N-methylcyclopropanecarbohydrazide (30 mg, 50%) as an off-white solid. 1H NMR (500 MHz, CDCl3): δ 9.24 (bs, 1 H), 8.50-8.41 (m, 1 H), 8.26-8.20 (m, 1 H), 8.02-7.94 (m, 2 H), 7.66-7.58 (m, 2 H), 7.39 (d, J=7.2 Hz, 2 H), 7.14 (d, J=7.2 Hz, 2 H), 3.28 (s, 3 H), 3.39-3.12 (m, 1 H), 2.63-2.56 (m, 1 H), 1.84-1.78 (m, 1 H), 1.49-1.38 (m, 1 H), 1.37 (s, 9 H). MS: M+H: m/z=386.2 and HPLC: 91%, (Condition-G).
