In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 22536-66-9, name is 2-Chloropyrimidine-4-carboxamide, the common compound, a new synthetic route is introduced below. Computed Properties of C5H4ClN3O
To a solution of 0.07 g (0.19 mmol, 1.0 eq.) of(S)-1-amino-N-(3-chloro-4-fluorophenyl)-7- fluoro-2,3 -dihydro- 1H-indene-4-carboxami de hydrochloride (Vild) and 30 mg (0.21 mmol, 1.10 eq.) of 2-chloropyrimidine-4-carboxamide in 2 mL of NIVIP was added 0.07 ml (0.39mmol, 2.0 eq.) of N,N-diisopropylethylamine, and the mixture was subjected to microwave irradiation maintaining a reaction temperature of 130 C for 1 h. The mixture was diluted with 50 mL of ethyl acetate and washed 2 x 20 ml of water followed by 10 mL of brine. The organic phase was dried (Na2SO4), filtered and the solvent was removed in vacuo. The residue was purified by flash chromatography (Si02, eluting with a linear gradient of 0-30%ethyl acetate/hexanes) to provide 24 mg (0.05 mmol, 29%) of(S)-2-((4-((3-chloro-4- fluorophenyl)carbamoyl)-7-fluoro-2,3 -dihydro- 1H-inden- 1 -yl)amino)pyrimidine-4- carboxamide (104). LCMS: m/z found 444. 1/446.1 [M+H]. HPLC: RT = 4.13 mm (Method A); ?H NIVIR (300 MFIz, Methanol-d4) 8.50 (d, 1H), 7.93 (dd, 1H), 7.61-7.72 (m, 1H), 7.50- 7.60 (m, 1H), 7.16-7.28 (m, 2H), 7.03 (t, 1H), 5.88-5.95 (m, 1H), 3.07-3.48 (m, 2H), 2.55-2.66(m, 1H),2.10(m, 1H).
The synthetic route of 22536-66-9 has been constantly updated, and we look forward to future research findings.
