624-76-0, A common heterocyclic compound, 624-76-0, name is 2-Iodoethanol, molecular formula is C2H5IO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
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) delta 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).
The synthetic route of 2-Iodoethanol has been constantly updated, and we look forward to future research findings.
