실험 절차
To the solution of A4 (100 mg, 0.24 mmol) and DIEA (140 mg, 0.96 mmol) in 10 mL of DMF, was added (1S,2S)-2-Amino-cyclohexanol (45 mg, 0.29 mmol). The reaction mixture was stirred at room temperature for several hours. LC/MS was applied to determine completion of the reaction. DMF was evaporated under reduced pressure and the residue was precipitated with 5% diethylamine/methanol (25 mL) under sonication. The solid was collected by filtration and washed with methanol), dried under vacuum to provide to provide title compound (70 mg, 74% yield) as orange solid. 1H NMR (300 MHz, DMSO-d6): δ=13.62 (s, 1H), 10.88 (s, 1H), 7.71-7.77 (m, 2H), 7.36-7.39 (d, 1H), 6.81-6.95 (m, 2H), 4.58-4.60 (d, 1H), 3.48-3.60 (m, 1H), 3.30-3.35 (m, 1H), 2.41-2.44 (ds, 6H), 1.88-1.90 (t, 2H), 1.62 (S, 2h), 1.23 (s, 4H).
