Reference of 31108-57-3, The chemical industry reduces the impact on the environment during synthesis 31108-57-3, name is 1H-Pyrazole-4-carbonitrile, I believe this compound will play a more active role in future production and life.
To a solution of IV-B8 (44 mg, 0.11 mmol) in acetone (2 mL) was added lH-pyrazole-4- carbonitrile (16 mg, 0.17 mmol) and K2C03 (48 mg, 0.34 mmol). After stirring at 25C for 12 h, the mixture was diluted with water (5 mL) and extracted with EtOAc (2 x 10 mL). The combined organic solution was washed with brine (5 mL), dried over anhydrous Na2S04, filtered and concentrated. The residue was purified by flash column (0-43% of EtOAc in PE) to give IV-B9 (22 mg, 49%) as a solid. (3084) 1HNMR (400 MHz, CDCl3) dH 7.86 (s, 1H), 7.81 (s, 1H), 5.08-5.02 (m, 1H), 4.94-4.87 (m, 1H), 2.63 (t, j= 8.8 Hz, 1H), 2.26-2.16 (m, 1H), 2.06-1.99 (m, 1H), 1.82-1.70 (m, 6H), 1.46- 1.17 (m, 15H), 0.91-0.83 (m, 2H), 0.65 (s, 3H). LC-ELSD/MS purity 99%, MS ESI calcd. for C24H33N302 [M+H]+396.2, found 396.2
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, 1H-Pyrazole-4-carbonitrile, other downstream synthetic routes, hurry up and to see.
