Electric Literature of 36650-74-5, The chemical industry reduces the impact on the environment during synthesis 36650-74-5, name is 1H-Pyrazole-3-carbonitrile, I believe this compound will play a more active role in future production and life.
To a solution of II-D12 (165 mg, 0.4 mmol) in acetone (5 mL) was added K2C03 (96.9 mg, 0.7 mmol) and lH-pyrazole-4-carbonitrile (65.4 mg, 0.7 mmol) at l5C. The reaction mixture was stirred for 16 hours at l5C. The reaction mixture was added into saturated NH4Cl (20 mL). The aqueous layer was extracted with EtOAc (3 x 20 mL). The combined organic layer was washed with saturated brine (50 mL), dried over anhydrous Na2S04, filtered and concentrated to give product. The residue was purified by combi flash (0-20% of EtOAc in PE) to give II-D13 (74.6 mg, 44.1%) as a solid. (1069) 1H NMR (400 MHz, CDCl3) dH 7.47 (d, J= 2.4 Hz, 1H), 6.72 (d, J= 2.4 Hz, 1H), 4.96 (dd, J = 17.6, 51.2 Hz, 2H), 3.52 (q, J = 6.8 Hz, 2H), 3.21 (s, 2H), 2.59 (t, J = 8.8, 1H), 2.25-2.10 (m, 2H), 1.90-1.60 (m, 6H), 1.55-1.10 (m, 18H), 1.05-0.80 (m, 5H), 0.68 (s, 3H); MS ESI calcd. for C29H42N302 [M-H20+H]+ 464, found 464.
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-3-carbonitrile, other downstream synthetic routes, hurry up and to see.
