Electric Literature of 1000522-43-9, Adding some certain compound to certain chemical reactions, such as: 1000522-43-9, name is 2-(5-Chloropyridin-2-yl)acetic acid,molecular formula is C7H6ClNO2, 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 1000522-43-9.
4-Cyclopropyl-[1,2,3]triazol-1-yl)acetic acid (Preparation 121 , 85 mg, 0.508 mmol) and (4-Aminopyridin-2-yl)-(7-tert-butyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)methanone (Preparation 29, 100 mg, 0.338 mmol) were dissolved in THF (5 mL), followed by the addition of Et3N (0.165 mL, 1 .18 mmol) and 1 -propylphosphonic acid cyclic anhydride (50% solution in EtOAc, 0.507 mL, 0.845 mmol) at room temperature. The resultant mixture was stirred at room temperature for 16 hours and then diluted with ethyl acetate (20 mL). The organic layer was washed with aqueous saturated NaHCO3 solution, water, brine, dried over sodium sulphate and evaporated to dryness in vacuo. The crude residue was purified using preparative TLC eluting with 3% MeOH in DCM to afford the title compound as brown solid in 25% yield, 37 mg. 1H NMR (400 MHz, DMSO-d6): delta ppm 0.72-0.73 (m, 2H), 0.90-0.93 (m, 2H), 1 .82 (s, 9H), 1 .95-1 .98 (m, 1 H), 5.29 (s, 2H), 7.82 (d, 1 H), 7.86 (s, 1 H), 8.23 (s, 1 H), 8.65 (d, 1 H), 8.97 (s, 1 H), 9.20 (s, 1 H), 9.59 (s, 1 H), 1 1 .16 (br, 1 H). LCMS Rt = 3.17 minutes MS m/z 445 [M+H]+. The following examples were prepared according to Method 2 (Example 36) followed by method 1 Step 2 using 4M HCI in dioxan, using (4-aminopyridin-2-yl){7-[(1 R)-1 -methyl- 2-(tetrahydro-2H-pyran-2-yloxy)ethyl]-7H-pyrrolo[2,3-d]pyrimidin-5-yl}methanone (Preparation 22) or (4-aminopyridin-2-yl){7-[(1 S)-1 -methyl-2-(tetrahydro-2H-pyran-2- yloxy)ethyl]-7H-pyrrolo[2,3-d]pyrimidin-5-yl}methanone (Preparation 23) and the appropriate acetic acids.
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. 1000522-43-9, 2-(5-Chloropyridin-2-yl)acetic acid, other downstream synthetic routes, hurry up and to see.
