I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21905-86-2, help many people in the next few years.318276-74-3

In an article, published in an article,once mentioned the application of 318276-74-3,molecular formula is C10H8N2O2, is a conventional compound. this article was the specific content is as follows. 318276-74-3

A solution of the compound from example 3d) (345 mg; 1.8 mmol.) in anhydrous tetrahydrofuran (20.0 mL) was cooled to 5 oC for the portionwise addition of solid lithium aluminumhydride (70.0 mg; 1.8 mmol.) and stirred at 5 0C for 1 h. The mixture was quenched by the addition of ethyl acetate (50.0 mL) then water (5.0 mL), filtered through a pad of Celite and evaporated. The residue was dissolved in ethyl acetate (50.0 mL) and treated with manganese dioxide (0.50 g) and stirred at room temperature for 2 h. The mixture was filtered through a pad of Celite and evaporated to afford the title EPO compound (169 mg; 60%) as a brown powder which was used directly in the following step without further purification,

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21905-86-2, help many people in the next few years.318276-74-3
