Adding a certain compound to certain chemical reactions, such as: 4584-46-7, name is 2-Chloro-N,N-dimethylethanamine 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 4584-46-7, Recommanded Product: 4584-46-7
A mixture of 2-(2,4-dimethoxy-benzyl)-4-hydroxy-isoindole-1,3-dione (317 mg, 1.01 mmol), 2- dimethylaminoethyl chloride hydrochloride (160 mg, 1.11 mmol) and potassium carbonate (350 mg, 2.5 mmol) in DMF (4 ml_) was heated at 6O0C for 18 hours. The mixture was concentrated in vacuo, taken up in ethyl acetate and extracted twice with 1 N hydrochloric acid. The aqueous extracts were made basic with solid potassium carbonate and extracted with ethyl acetate (*2). The combined organic extracts were washed with brine, dried (MgSO4) and concentrated to give the title compound (236 mg, 61 %) as an off-white solid. 1H NMR (methanol-d4) 7.73 (1 H, t), 7.44-7.40 (2H1 m), 7.02 (1 H, d), 6.51 (1 H, d), 6.42 (1 H, dd), 4.72 (2H, s), 4.33 (2H, t), 3.80 (3H, s), 3.76 (3H, s), 2.87 (2H, t), 2.40 (6H, s). MS: [M+H]+ 385.
