Reference of 105252-99-1, Adding some certain compound to certain chemical reactions, such as: 105252-99-1, name is 4-Amino-6-fluoropyridin-2(1H)-one,molecular formula is C5H5FN2O, 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 105252-99-1.
Step a: A suspension of 4-ammno-6-fluoropyridin-2(1H)-one (570 mg, 4.45 mmol), K2C03 (922 mg, 6.67 mmol), and Mel (278 jiL, 4.45 mmol) in EtOH (15 mL) was stirred for 15 h at 70 C. After cooling to RT, the reaction mixture was filtered and rinsed with EtOH. The filtrate was suspended in water (40 mL) and extracted with EtOAc (2 x 40 mL) and trifluoroethanol (10% in DCM, 8 x 40 mL). The combined organic extracts were dried over Mg504, filtered, and the volatiles were removed under reduced pressure. The residue was purified by silica chromatography (0 to 10% gradient of MeOH/DCM) to give 4-amino-6-fluoro- 1-methylpyridin-2(1H)-one (356 mg, 2.51 mmol) as a white solid. MS m/z 142.8 (M+H).
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. 105252-99-1, 4-Amino-6-fluoropyridin-2(1H)-one, other downstream synthetic routes, hurry up and to see.
