Reference of 4318-56-3, Adding some certain compound to certain chemical reactions, such as: 4318-56-3, name is 6-Chloro-3-methylpyrimidine-2,4(1H,3H)-dione,molecular formula is C5H5ClN2O2, 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 4318-56-3.
2-(6-Chloro-3-methyl-2,4-dioxo-3,4-dihydro-2H-pyrimidin-1-ylmethyl)-4-fluoro-benzonitrile (6) A mixture of crude 3-methyl-6-chlorouracil (5) (0.6 g, 3.8 mmol), 2-Bromomethyl-4-fluorobenzonitrile (0.86 g, 4 mmol) and K2CO3 (0.5 g, 4 mmol) in DMSO (10 mL) was stirred at 60 C. for 2 hours. The reaction was diluted with water and extracted with EtOAc. The organics were dried over MgSO4 and the solvent removed. The residue was purified by column chromatography. 0.66 g of the product was obtained (yield: 60%). 1H-NMR (400 MHz, CDCl3): delta 7.73 (dd, J=7.2, 8.4 Hz, 1H), 7.26 (d, J=4.0 Hz, 1H), 7.11-7.17 (m, 1H), 6.94 (dd, J=2.0, 9.0 Hz, 1H), 6.034 (s, 2H), 3.39 (s, 3H). MS (ES) [m+H] calc’d for C13H9ClFN3O2, 293.68; found 293.68.
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. 4318-56-3, 6-Chloro-3-methylpyrimidine-2,4(1H,3H)-dione, other downstream synthetic routes, hurry up and to see.
