Extracurricular laboratory: Synthetic route of 872-82-2

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 872-82-2.

These common heterocyclic compound, 872-82-2, name is 2-(1H-Imidazol-5-yl)ethanol, 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. 872-82-2

Preparation 32 4-(2-((tert-butyldiphenylsilyl)oxy)ethyl)-1H-imidazole A solution of 2-(1H-imidazol-4-yl)ethanol (1.24 g, 11.1 mmol) in DMF (10 mL) was treated with imidazole (1.51 g, 22.1 mmol) and TBDPSCl (3.12 mL, 12.2 mmol) and the mixture was stirred at RT for 2 h. The mixture was then poured onto H2O and extracted with AcOEt. The combined org. layers were dried over Na2SO4, filtered and concentrated in vacuo. Purification by flash chromatography (SiO2, AcOEt/heptane 0:100 to 100:0) gave the title compound (1.6 g). UPLC-MS: MS 351.2 (M+H+); UPLC rt 1.02 min.

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 872-82-2.
