Reference of 178421-21-1, Adding some certain compound to certain chemical reactions, such as: 178421-21-1, name is Ethyl 6-chloro-5-methylpicolinate,molecular formula is C9H10ClNO2, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 178421-21-1.
Step 1: 2-Carboxamido-5-methyl-6-chloropyridine (IX). Dissolve 26 g of 2-ethoxycarbonyl-5-methyl-6-chloro-pyridine (crude oil containing about 60% of ester) in 130 ml of methanol.Add 200 ml of 32% aqueous ammonia and stir overnight at room temperature.The product is recovered by filtration and gives, after washing with water and drying under vacuum, 13 g of white crystals. m.p.=146 C.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 178421-21-1, Ethyl 6-chloro-5-methylpicolinate, other downstream synthetic routes, hurry up and to see.
