Adding a certain compound to certain chemical reactions, such as: 68327-04-8, (1S,2S)-2-Aminocyclopentanol hydrochloride, 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, Formula: C5H12ClNO, blongs to alcohols-buliding-blocks compound. Formula: C5H12ClNO
A mixture of 5,6-dimethyl-4-(4-(1-methyl-1H-pyrazol-3-yl)benzyl)picolinic acid (30.0 mg), (1S,2S)-2-aminocyclopentanol hydrochloride (19.3 mg), WSC (26.8 mg), HOBt (18.9 mg) and triethylamine (28.3 mg) in DMF (1 mL) was stirred at room temperature overnight. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution and extracted twice with ethyl acetate. The obtained organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/methanol), and solidified with ethyl acetate-hexane to give the title compound (30.0 mg). 1H NMR (300 MHz, CDCl3) delta1.60-1.96 (4H, m), 2.03-2.18 (1H, m), 2.22 (3H, s), 2.24-2.34 (1H, m), 2.53 (3H, s), 3.94 (3H, s), 3.95-4.03 (1H, m), 4.05 (2H, s), 4.08-4.18 (1H, m), 4.71 (1H, brs), 6.49 (1H, d, J = 1.7 Hz), 7.11 (2H, d, J = 8.0 Hz), 7.36 (1H, d, J = 1.9 Hz), 7.69 (2H, d, J = 8.0 Hz), 7.88 (1H, s), 8.20 (1H, brs).
The synthetic route of 68327-04-8 has been constantly updated, and we look forward to future research findings.
