Reference of 1758-46-9, These common heterocyclic compound, 1758-46-9, name is 2-Phenoxyethylamine, 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 6] Compound D (150 mg, 483 mumol), 2-phenoxyethylamine (127 mul) and sodium hydrogencarbonate (400 mg) were added to DMSO (3 ml), and the mixture was stirred at 100°C for 27 hr. After stirring, the reaction mixture was added dropwise to cold water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and concentrated, and the residue was washed by suspending in ethyl acetate to give the object compound of 2-(2-phenoxyethylamino)-6-(5-methyl-1H-pyrazol-3-ylamino)-4-(pyridin-3-yl)nicotinonitrile (82 mg). 1H-NMR (400MHz, DMSO-d6) delta (ppm): 12.06 (1H,br-s), 10.22 (1H,br-s), 8.72-8.69(2H,m), 7.98(1H,dd), 7.65(1H,dd), 7.29-7.23(2H,m), 6.96-6.90(3H,m),6.16(1H,br-s),4.23(2H,t),3.67(2H,t),2.22(3H,s). m/z=412 (M+H)
The synthetic route of 1758-46-9 has been constantly updated, and we look forward to future research findings.
