Related Products of 5413-85-4 , The common heterocyclic compound, 5413-85-4, name is 5-Amino-4,6-dichloropyrimidine, molecular formula is C4H3Cl2N3, 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 144; N-(4-Ethoxypyrimidin-5-yl)-4-(3-phenyl-1,2,4-thiadiazol-5-yl)piperazine-1-carboxamide; (4) 4-Ethoxypyrimidine-5-amine; A mixture of 5-amino-4,6-dichloropyrimidine (5.00 g, 30.5 mmol), tetrahydrofuran (100 ml), sodium hydroxide (2.44 g, 61.0 mmol), ethanol (100 ml) and 10% palladium-carbon (500 mg) was stirred under a hydrogen atmosphere at room temperature for 1 day, insolubles were filtered off and an organic layer was separated. The organic layer was dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure to obtain the desired product (4.00 g, 94.3%) as an oil. 1H-NMR (CDCl3) delta; 1.43 (3H, t, J = 6.9 Hz), 3.75 (2H, br s), 4.48 (2H, q, J = 6.9 Hz), 7.92 (1H, s), 8.24 (1H, s).
The synthetic route of 5413-85-4 has been constantly updated, and we look forward to future research findings.
