Procedure
Compound 520 (37 mg, 0.08 mmol) was dissolved in MeOH (2 mL), NH4Cl (29 mg, 0.55 mmol) and Zn-dust (72 mg, 1.10 mmol) were added. Reflux for 0.5 h, allowed to cool to RT and filtered. Purified by flash chromatography using DCM:MeOH (v:v=95:5) as the eluent, affording the title compound. 13C NMR (CD3OD) δ 192.4, 156.5 (d), 156.2 (d), 153.1, 144.8, 136.3, 135.1, 129.9 (d), 128.4, 128.1, 127.1, 126.8, 120.8 (d), 119.6, 118.0 (d), 117.7, 116.5 (d), 115.8, 112.5, 71.7, 71.2, 64.0
