Adding a certain compound to certain chemical reactions, such as: 25016-20-0, name is 1-Methyl-1H-pyrazole-3-carboxylic acid, belongs to pyrazoles-derivatives compound, 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 25016-20-0, Computed Properties of C5H6N2O2
Acid R2a (13.9 mg; 0.1 10mmol) is dissolved in DMF (2 mL) and TEA (51.2 muIota 0.367 mmol) and TBTU (34.0 mg; 0.1 10 mmol) are added and the mixture is stirred for 15 mins. The Boc de-protected macrocyclic amine hydrochloride Cf is dissolved in DMF (1.0 mL) and added to the acid solution and stirred at RT overnight. The resulting solution is filtered through a Millex filter and purified by prep HPLC (ammonium bicarbonate/MeOH). The pure fractions are combined, concentrated, frozen and lyophilized to provide compound 1003.FIA M.S.(electrospray) : 822.5/ 824.5 (M-H)- , 824.4/ 826.3 (M+H)+Retention time (min): 7.0 min1H NMR (400 MHz,DMSO-d6): delta 10.83 (s, 1 H) , 8.92 (s, 1 H), 7.86 (d, 1 H, J = 8.6 Hz), 7.79 (d, 1 H, J = 5.1 Hz), 7.75 (d, 1 H, J = 2 Hz), 7.29 (d, 1 H, J = 8.6 Hz), 6.57 (s, 1 H), 6.53 (d, 1 H, J = 2 Hz), 5.67- 5.55 (m, 1 H), 5.55- 5.44 (m, 2H), 5.12- 5.00(m, 1 H), 4.62- 4.50 (m, 2H), 4.45- 4.37 (m, 1 H), 4.05- 3.95 (m, 1 H), 3.88 (s, 3H), 2.66 (s, 3H), 2.40- 2.25 (m, 2H), 2.03- 1.87 (m, 1 H), 1.87-1.72 (m, 1 H), 1.60- 1.47(m, 3H), 1.47-1.15 (m, 19H), 0.95- 0.78 (m, 2H).
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, 1-Methyl-1H-pyrazole-3-carboxylic acid, other downstream synthetic routes, hurry up and to see.
