2 Sep 2021 News Some tips on 2516-33-8

With the rapid development of chemical substances, we look forward to future research findings about 2516-33-8.

The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 2516-33-8, name is Cyclopropylmethanol. This compound has unique chemical properties. The synthetic route is as follows. Recommanded Product: 2516-33-8

General procedure: To 259 mg (26.9 mmol) pyrimidin-5-ol (J. Chem. Soc. 1956, 2033) in 200 mL DMF are added 108 mg (26.9 mmol) sodium hydride (60% dispersion in mineral oil). The mixture is stirred for 20 mm at r.t.. After that time, 500 mg (22.4 mmol) 2-fluoro-4-iodopyridine are added and the mixture is stirred for 12 h at 80 C. Subsequently the mixture is poured into water and extracted with ethyl acetate (3x). The combined organic layers are washed with brine. After drying over sodium sulphate, the solvent is removed in vacuo and the residue is purified by column chromatography (silica gel; heptane/EtOAc, 100/0 – 40/60).C9H6IN3O (M = 299.1 g/mol)ESI-MS: 300 [M+H]+ Rt(HPLC) : 2.87 min (method C) For the example XXVIII.3 THF is used as solvent and the reaction mixture is stirred at r.t. over night.

With the rapid development of chemical substances, we look forward to future research findings about 2516-33-8.
