In an article, published in an article,once mentioned the application of 21905-86-2,molecular formula is C9H6N2O2, is a conventional compound. this article was the specific content is as follows. 21905-86-2
EXAMPLE 42 2-(2-ethoxyethoxy)ethyl cinnoline-4-carboxylate (42) 1.07 g of CDIT was added to a mixture of 1.04 g of 1 in 70 ml of dry THF under nitrogen, the mixture was stirred at room temperature for 4 hours, 1.6 g of 2-(2-ethoxyethoxy)ethanol and 0.032 g of sodium methoxide were added and the mixture was stirred at room temperature over a weekend. Then the solvent was stripped, and the residue was dissolved in methylene chloride. The solution was washed with water, dried (MgSO4) and stripped of solvent. The residue was flash-chromatographed on silica gel, using a 1:4 v:v mixture of ethyl acetate and methylene chloride as eluent, to give 42, as a yellow oil.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.21905-86-2, you can also check out more blogs about21905-86-2
