Versuchsvorschrift

Compound 512 (38 mg, 0.1 mmol) was dissolved in acetonitrile (2 mL) in a reaction vial. 3-Chloro-propan-1-ol (11 μL, 0.12 mmol), K2CO3 (17 mg, 0.12 mmol) and NaI (cat. amount) were added. The reaction vial was flushed with argon, closed and then stirred at 130° C. for 20 min. in a microwave oven. The reaction mixture was allowed to cool to RT and then poured into a mixture of EtOAc/water. The aqueous phase was acidified with HCl (4N) and the layers were separated. The aqueous phase was extracted with more EtOAc. The organic phases were combined, dried (MgSO4), filtered and concentrated in vacuo affording the crude product. Purified by continuously gradient flash chromatography using EtOAc/petroleum ether (40-60)(v:v=1:3 to 1:1) as the eluent, affording the title compound as a yellow solid. 13C NMR (CDCl3) δ 190.8, 159.1 (dd), 155.6 (dd), 155.3 (d), 155.0 (d), 148.0, 134.7, 133.0, 129.4, 127.9 (d), 124.4 (m), 120.4 (d), 117.1 (d), 116.0, 115.1 (d), 112.8, 111.6 (dd), 104.9 (dd), 66.3, 60.0, 32.0
