Adding a certain compound to certain chemical reactions, such as: 150349-36-3, name is 3-(N-Boc-N-methylamino)propylamine, belongs to amides-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 150349-36-3, HPLC of Formula: C9H20N2O2
Example A42; a) Preparation of intermediate 149; Pd/C 10% (4 g) was suspended in MeOH (200 ml) under N2 atmosphere. A 4% thiophene solution (4 ml) was added. The mixture was stirred at 25 0C under H2 atmosphere for pre-hydrogenation. First iV-(3-aminopropyl)-N-methylcarbamic acid 1,1-dimethylethyl ester (0.106 mol) and then benzaldehyde (0.106 mol) was added. The reaction mixture was stirred and hydrogenated at 25 0C under H2 atmosphere. After uptake of H2 (1 equiv), formaldehyde (0.106 mol) was added and the reaction mixture was hydrogenated further. After uptake of H2 (1 equiv), the catalyst was filtered off over dicalite and the filtrate was evaporated. The residue was purified over silica gel (eluent: DCM/CH3OH 95/5). The product fractions were collected and the solvent was evaporated to give an oil, yielding 26.5 g (71.7%) of intermediate 149.
