Adding a certain compound to certain chemical reactions, such as: 121492-06-6, name is N-Boc-(2-Aminoethyl)-N-methylamine, 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 121492-06-6, name: N-Boc-(2-Aminoethyl)-N-methylamine
EXAMPLE H-l 4 Example H-14 N-ethyl-N-(2-((4-(2-hvdroxypropan-2-yl)pyrinudin-2-yl)(methyl)aniino)ethyl)-2- isopropoxynicotinamide Step 1 : tert-butyl (2-(((benzyloxy)carbonyl)amino)ethyl)(methyl)carbamate (H-7) To a solution of tert-butyl (2-aminoethyl) (methyl)carbamate (5.0 g, 28.7 mmol) in THF (100 mL) was added NaHC03 (12.1 g, 143.5 mmol) at 0 C. The resulting mixture was stirred at the same temperature for 15 min. Cbz-Cl (5.9 g, 34.4 mmol) was added dropwise. The mixture was stirred at RT overnight, then filtered and the filtrate was concentrated in vacuo. The residue was purified by combiflash (10% EtOAc in petroleum ether) to give the title compound H-7. LRMS m/z (M+H) 309.1found, 309.4 required.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, N-Boc-(2-Aminoethyl)-N-methylamine, other downstream synthetic routes, hurry up and to see.
