Versuchsvorschrift

Compound 4a (617 mg, 4.6 mmol) was reacted with 2-Iodoethanol (0.54 mls, 6.9 mmol) and diisopropylethylamine (1.2 mls, 6.9 mmol) in ACN (20 mls) at 30° C. for 48 hours. The solvent was evaporated and the residue was purified by silica gel column chromatography with hexane and EtOAc to provide the intermediate 4b (483 mg, 2.7 mmol, 59% yield) as a light brown oil. HRMS (ESI, positive) m/z calcd. for C11H18N1O1 [M+H]+: 180.13829, found: 180.13829. 1H NMR (400 MHz, CDCl3) δ 7.28-7.19 (t, J=8.0 Hz, 2H), 6.92-6.85 (d, J=8.2 Hz, 2H), 6.83-6.75 (t, J=7.3 Hz, 1H), 4.03-3.88 (hept, J=6.6 Hz, 1H), 3.70-3.62 (t, J=6.2 Hz, 2H), 3.34-3.24 (m, 2H), 1.19-1.12 (d, J=6.6 Hz, 6H).
