Adding a certain compound to certain chemical reactions, such as: 6276-54-6, name is 3-Chloropropan-1-amine hydrochloride, belongs to chlorides-buliding-blocks compound, 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 6276-54-6, Quality Control of 3-Chloropropan-1-amine hydrochloride
Step 1: Synthesis of 1-azido-3-aminopropane 1 Synthesis is carried out according to the following reaction scheme: This compound was obtained according to a synthesis previously described by Carboni, B. et al. (Macromolecules, Vol. 40, No. 16, 2007/Carboni, B.; Benanlil, A.: Vaultier, M. J. Org. Chem. 1993, 58, 3736). An aqueous solution (30 mL) of 3-chloropropylamine hydrochloride (4 g; 30.8 mmol) and of sodium nitride (6 g; 92.3 mmol, 3 equiv) is heated at 80 C. for 17 h. After evaporation of the water, the reaction mixture is put in an ice bath. 50 mL of diethyl ether and 4 g of potassium hydroxide are added. The phases are separated. The product is extracted from the aqueous phase with 2*20 ml, of diethyl ether. The organic phase is then dried over magnesium sulfate and filtered. After evaporation, the oil obtained is purified by distillation at reduced pressure. (2.46 g; yield: 80%; colorless oil) 1H NMR (300 MHz, CDCl3), delta (ppm): 3.33 (t, 2H, CH2N3); 2.55 (t, 2H, Cl2NH2); 2.34 (s, 2H, NH2); 1.55 (q, 2H, CH2CH2CH2). FT-IR (ATR, cm-1): 2100 (N3)
