Reference of 121492-06-6, These common heterocyclic compound, 121492-06-6, name is N-Boc-(2-Aminoethyl)-N-methylamine, its 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.
Example 95; l,l-dimethylethyl (2-{r8-(2.6-difluorophenvn-4-f5-frf4- fluorophenyl)aminolcarbonyl}-2-methylphenv?-7-oxo-7,8-dihvdropyrido[2.3-^rhoyrimidin-2-yl]amino|ethyl)methylcarbarnateTo a solution of 3-[8-(2,6-difluorophenyl)-2-(methylsulfmyl)-7-oxo-7,8- dihydropyrido[2,3-d]pyrimidin-4-yl]-N-(4-fluorophenyl)-4-methylbenzamide (50 mg, 0.09 mmol) in DCM (5 niL) was added 1,1-dimethylethyl (2-aminoethyl)- methylcarbamate (0.09 mL, 0.5 mmol). The resultant mixture was stirred at room temperature overnight. The mixture was concentrated under vacuo. Flash chromatography (90% CH2Cl2 / 7% MeOH / 3% NH4OH) then provide the title compound (61 mg, 100%). LC-MS (ES) m/z 659 (M+H)+; 1H-NMR(CDCl3) delta 1.39 (s, 9H), 1.70 (br, IH), 2.32 (s, 3H), 2.65 (s, 2H), 2.82 (s, 2H), 3.22 (s, 3H), 3.60 (br, IH), 6.34 (d, IH)5 7.03 (m, 4H)5 7.34 (m, IH), 7.48 (m. 2H), 7.64 (m, IH), 7.84 (m, 2H)5 8.14 (d, IH).
Statistics shows that N-Boc-(2-Aminoethyl)-N-methylamine is playing an increasingly important role. we look forward to future research findings about 121492-06-6.
