Related Products of 58483-98-0, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.58483-98-0, name is 2-Amino-5-bromonicotinamide, molecular formula is C6H6BrN3O, molecular weight is 216.04, as common compound, the synthetic route is as follows.
A mixture of 2-amino-5-bromonicotinamide (100 mg, 0.46 mmol), 3-fluorobenzaldehyde (69 mg, 0.56 mmol), NaHSO3 (40 mg, 0.38 mmol), 4-methylbenzene sulfonicacid (15 mg, 0.05 mmol) in DMAc (3 mL) was stirred at 115C for 1.5 h, then additional NaHSO3(40 mg, 0.38 mmol) was added to the mixture. After 1.5 h, the third portion of NaHSO3 (40 mg,0.38 mmol) was added to the mixture. After being stirred overnight at 115C, the reaction mixturewas concentrated in vacuo, suspended in water and filtered to give the product of 6-bromo-2-(3-fluorophenyl)pyrido[2,3-d]pyrimidin-4(3H)-one (70 mg, yield: 47%), which was used for the nextstep without further purification. ?H-NMR (DMSO-d6, 400 MHz) 13.04 (br s, 1H), 9.07 (d, J2.8 Hz, 1H), 8.65 (d, J= 2.8 Hz, 1H), 8.08 (d, J= 8.0 Hz, 1H), 8.02 (dd, J= 9.6, 1.6 Hz, 1H), 7.607.68 (m, 1H), 7.457.54 (m, 1H). MS (M+H): 320/322.
Statistics shows that 58483-98-0 is playing an increasingly important role. we look forward to future research findings about 2-Amino-5-bromonicotinamide.
