Application of 179692-08-1<\/a>, These common heterocyclic compound, 179692-08-1, name is Ethyl 4-iodo-1H-pyrazole-5-carboxylate, 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.<\/p>\n

A suspension of Intermediate 74b (2.72 g, 10.2 mmol) in acetonitrile (27 mL) was treated with caesium carbonate (5.0 g, 15.3 mmol) then 2-(2- bromoethoxy)tetrahydro-2H-pyran (1.70 mL, 11.2 mmol) and the mixture was stirred at 60 C for 3.5 h. The mixture was evaporated in vacuo and the residue was partitioned between EtOAc and water. The aqueous layer was then extracted with EtOAc (2 x). The combined organic layers were washed with saturated aqueous sodium bicarbonate solution and brine, dried (Na2S04), filtered and evaporated in vacuo. The residue was purified by FCC, using 0-50% EtOAc in cyclohexane, isolating the lower running spot to give the title compound as a colourless glass (1.57 g, 39%). LCMS (Method 3): Rt 3.67 min, m\/z 417 [M+Na+].<\/p>\n

The synthetic route of 179692-08-1 has been constantly updated, and we look forward to future research findings.<\/p>\n
