Electric Literature of 73101-79-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 73101-79-8, name is 5-Ethoxy-6-methylpyridin-2-amine, molecular formula is C8H12N2O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
b) The product from part a) (19.0 g) was added dropwise to 5M sodium hydroxide solution (29 ml) and water (100 ml) keeping the temperature below 15 C. This solution was then added quickly to the solution of 5-ethoxy-6-methyl-pyridin-2-amine (20.0 g) in 4M hydrochloric acid (40 ml) and water (200 ml). This mixture was stirred at ambient temperature for 2 hours then filtered to give a solid which was recrystallized from IMS/water to give ethyl 2-(5-ethoxy-6-methylpyridin-2-ylaminomethylene)propionate, m.p. 118-122 C.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 73101-79-8, 5-Ethoxy-6-methylpyridin-2-amine.
