Related Products of 4535-90-4,Some common heterocyclic compound, 4535-90-4, name is 2-Chloro-N-methylethanamine hydrochloride, molecular formula is C3H9Cl2N, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
(ii) The white crystal 3 (1.0 g, 7.69 mmol) and sodium thiosulfate pentahydrate (1.91 g, 7.69 mmol) were added into 100 mL flask. MilliQ water (10 mL) was then added into the flask, and the reaction mixture was stirred at 120 C for 24 h under argon atmosphere. The reaction was then cooled to room temperature and the solvent was removed under reduced pressure. Hydrochloric acid (6.0 M, 25 mL) was added into the flask and the solution was stirred at 85 C for 3 h under argon atmosphere. The solvent was then removed, and 100 mL of dichloromethane and 15 mL of ethanol were added to extract the product. Sodium chloride and sulfate salts were precipitated from the solution. The salts were then filtered and the filtrate was concentrated to give product as a white solid (0.55 g, yield: 56.1%). The B monomer was extremely hygroscopic, which was needed to be stored in a dry oven. The 1H NMR and 13C NMR spectra of B monomer were shown in Fig. S4.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Chloro-N-methylethanamine hydrochloride, its application will become more common.
