실험 절차

To a solution of Compound (6) (8 mg, 0.02 mmol) in DCM (2.0 mL) was added acetic anhydride (0.1 mL) and pyridine (0.1 mL) and the mixture was stirred at ambient temperature for 16 h. The reaction mixture was then concentrated in vacuo and the residue partitioned between EtOAc (25 mL) and water (15 mL). The organic layer was separated and the aqueous layer was extracted with EtOAc (3×15 mL). The combined organics were washed with brine (15 mL), dried (MgSO4) and concentrated in vacuo (32 mg). The crude material was purified by reverse phase preparative LCMS: Acetonitrile/water (0.1% formic acid) to give Compound (8) (2.14 mg, 20%). ESI-MS m/z calculated for [M+H]+: 544.2. found: 544.1. 1H NMR (400 MHz, CD3CN) δ 7.85 (s, 1H), 7.63-7.54 (m, 4H), 7.40 (s, 1H), 7.05 (br s, 1H), 4.21-4.14 (m, 1H), 3.93 (td, J=8.9, 3.2 Hz, 1H), 3.76-3.67 (m, 3H), 3.49-3.43 (m, 1H), 3.11 (d, J=1.0 Hz, 3H), 2.93 (d, J=4.8 Hz, 3H), 2.77-2.64 (m, 1H), 2.46-2.36 (m, 1H), 1.95-1.81 (m, 2H), 1.73 (d, J=2.4 Hz, 3H), 1.14-1.02 (m, 3H), 0.69-0.58 (m, 1H).
