Electric Literature of 872-82-2,Some common heterocyclic compound, 872-82-2, name is 2-(1H-Imidazol-5-yl)ethanol, molecular formula is C5H8N2O, 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.
General procedure: A mixture of imidazole derivatives (4a-c, 10mmol), 4-amino-6-chloropyrimidine (1.30g, 10mmol), and K2CO3 (2.07g, 15mmol, for 5a) or Cs2CO3 (3.91g, 12mmol, for 5b-c) was stirred in DMF (20mL) at 100C (for 5a) or at 140C (for 5b-c) for 12h. Water (100mL) was then added. The mixture was extracted with EtOAc (3×50mL). The organic layer was separated and dried over Na2SO4. Removal of the solvents produced a residue which was purified using column chromatography and eluted with a mixture of MeOH:CH2Cl2 (1:30, v:v) to afford 5a-c.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-(1H-Imidazol-5-yl)ethanol, its application will become more common.
