2516-33-8 ,Some common heterocyclic compound, 2516-33-8, molecular formula is C4H8O, 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.

0.49 g (6.82 mmoi) cyclopropane methanol in 10 mL THF are charged with 0.42 g (11.4 mmoi) NaH and the reaction mixture is stirred at r.t. for 20 min. Then 1.00 g (5.68 mmoi) 5-bromo-2-fluoropyridine are added and the mixture is stirred at r.t. over night. The reaction is quenched by the addition of water and extracted with EtOAc. The organic layers are combined, dried over MgS04l filtered and the solvent is removed in vacuo. The crude product is purified by HPLC (MeOH/H20/FA). CgH-ioBrNO (M= 228.1 g/mol) ESI-MS: 228/229 [M+H]+ Rt (HPLC):1.14 min (method C)

According to the analysis of related databases, 2516-33-8, the application of this compound in the production field has become more and more popular.

2516-33-8, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 2516-33-8 as follows.

General procedure: The gas-phase oxidation of alcohols is performed on a fixed-bed quartz tube reactor (600mm length by 14 mm inner diameter) under atmospheric pressure. Catalyst used in each test is 0.27 g (200-300 mesh). Other conditions are described in the previous literature elaborately [16]. The products are analyzed by Gas Chromatography (Shimadzu GC-2014 with a Rtx-5 column) as well as GC-MS (Agilent 6890 equipped with a HP-5 column).

The chemical industry reduces the impact on the environment during synthesis 2516-33-8, I believe this compound will play a more active role in future production and life.
