Some common heterocyclic compound, 102-49-8, name is 3,4-Dichlorobenzylamine, molecular formula is C7H7Cl2N, 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. Recommanded Product: 3,4-Dichlorobenzylamine
Methyl 6-(3,4-dichlorobenzylamino)nicotinate A mixture of (3,4-dichlorophenyl)methanamine (1.010 mL, 7.58 mmol), TEA (1.218 mL, 8.74 mmol), and methyl 6-chloronicotinate (1 g, 5.83 mmol) in ethanol (29 mL) was heated at 120° C. for 5 min in a microwave oven. The reaction mixture was further heated at 100° C. for 54 h, then concentrated. The residue was purified by flash chromatography on silica gel using 5-35percent ethyl acetate in hexanes. The desired fractions were concentrated to give methyl 6-(3,4-dichlorobenzylamino)nicotinate as a pale yellow solid (0.55 g, 33percent). 1H NMR (400 MHz, CHLOROFORM-d) delta ppm 8.77 (1H, s), 8.01 (1H, dd, J=8.78, 2.01 Hz), 7.33-7.52 (2H, m), 7.19 (1H, d, J=8.03 Hz), 6.37 (1H, d, J=8.78 Hz), 5.37 (1H, br. s.), 4.58 (2H, d, J=6.02 Hz), 3.88 (3H, s). LCMS: R.T.=2.81; [M+H]+=311.18.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 102-49-8, its application will become more common.
