The synthetic route is as follows.
Example 91 2-Ethyl-2,4,5,6-tetrahydrocyclopenta[c]pyrazol-3-amine (CF91) 2-Oxocyclopentanecarbonitrile (1.5 g, 14 mmol), sodium acetate (3.4 g, 42 mmol), and ethyl hydrazine-oxalate (4.2 g, 28 mmol) were mixed in ethanol, and the mixture was heated at reflux for overnight. The reaction mixture was cooled to room temperature and ethanol was removed on a rotary evaporator. Water was added and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over anhydrous sodium sulfate, and concentrated on a rotary evaporator. The remaining residue was purified by flash column chromatography to yield CF91 in 1.03 g. 1H NMR (300 MHz, CDCl3): 3.92 (q, J=7.23 Hz, 2H), 3.40-3.20 (m, 2H, NH), 2.62 (t, J=7.19 Hz, 2H), 2.54-2.44 (m, 2H), 2.40-2.28 (m, 2H), 1.38 (t, J=7.24 Hz, 3H). ESI-MS calculated for C8H14N3 [M+H]+=152.12; Observed: 152.33
The chemical industry reduces the impact on the environment during synthesis Cyclopentanone-2-carbonitrile. I believe this compound will play a more active role in future production and life.
