Reference of 51572-93-1, 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. 51572-93-1 name is O-(2,4-Dichlorobenzyl)hydroxylamine hydrochloride, This 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.
General procedure: To a solution of 3ae3e (1 mmol) in anhydrous ethanol (10 mL),corresponding O-benzylhydroxylamine hydrochloride (1 mmol)and NaOAc (1.2 mmol) were added and the resulting solution wasstirred at the room temperate for 3 h. The mixture was concentratedand taken in ethyl acetate (20 mL), washed with water(20 mL), saturated sodium chloride solution (20 mL) and dried oversodium sulfate. The resulting solution was concentrated and thepurification of the residue by recrystallization from ethanol yieldedthe desired compounds 4a-4t
At the same time, in my other blogs, there are other synthetic methods of this type of compound, O-(2,4-Dichlorobenzyl)hydroxylamine hydrochloride, and friends who are interested can also refer to it.
