New learning discoveries about 13078-79-0

In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 13078-79-0 as follows. Recommanded Product: 2-(3-Chlorophenyl)ethanamine

ii) N3-[2-(3-Chlorophenyl)ethyl]-N-(2,2-dimethylpropyl)-N-(2-{[2-(4-hydroxy-2-oxo-2,3- dihydro-1 ,3-benzothiazol-7-yl)ethyl]amino}ethyl)-beta-alaninamide bis-trifluoroacetic acid salt; Example 7 step i) (110 mg) was dissolved in ethanol (1.5 ml), 3-chlorophenethylamine (101 mg, 90 ul) was added and the mixture was stirred at 5O0C for 18 h. The solvents were removed in vacuo and the residue was re-dissolved in dichloromethane (0.5 ml). This solution was cooled in an ice/water bath, hydrogen bromide 30 wt % solution in acetic acid (0.5 ml) was added, and the mixture was stirred at room temperature for 2 h. Toluene (1 ml) was added to the reaction and all solvents were removed in vacuo. The residue was azeotroped with toluene, then ethanol (x2) before being purified by reverse phase HPLC (5-45% acetonitrile in aqueous TFA) to give the title compound (62 mg).1H NMR delta (DMSO) 11.76-11.72 (IH, m), 10.16-10.12 (IH, m), 8.84-8.76 (IH, m), 8.68-8.48 (3H, m), 7.40-7.31 (3H, m), 7.27-7.22 (IH, m), 6.88-6.83 (IH, m), 6.77-6.73 (IH, m), 3.59 (2H, t), 3.28-3.07 (1OH, m), 2.95 (2H, t), 2.87-2.75 (4H, m), 0.98-0.87 (9H, m). MS (Multimode +) 533 [(M-salt)+H]+
