실험 절차
To a solution of methyl 3-benzyloxy-4-oxo-5,6,7,8-tetrahydro-4H-pyrazolo[1,5-a][1,4]diazepine-2-carboxylate (50 mg, 0.159 mmol) in MeOH (2 mL) was added aqueous 1M NaOH (159 μL, 0.159 mmol). The reaction was stirred at room temperature for 4 hours, treated with additional aqueous 1N NaOH (159 μL, 0.159 mmol), and stirred at room temperature overnight. Aqueous 1N HCl (318 μL, 0.318 mmol) was added to the solution, and the solvents were removed in vacuo to afford the title product. 1H NMR (400 MHz, CD3OD) δ 7.39-7.36 (m, 2H), 7.32-7.28 (m, 3H), 5.24 (s, 3H), 4.38-4.34 (t, 2H), 2.90-2.86 (t, 2H), 2.13-2.06 (dt, 2H); ES MS (M+1)=302.
