| | 3,3-Difluoropyrrolidine hydrochloride Usage And Synthesis |
| Chemical Properties | Beige solid | | Uses | 3,3-Difluoropyrrolidine hydrochloride can be used as a building block in the synthesis of:
- Triazole substituted prolyl difluoropyrrolidines as potential inhibitors of dipeptidyl peptidase-4.
- Dual leucine zipper kinase (DLK) inhibitors.
It can be also used as a reactant in the preparation of cyclic and acyclic β-aminofluoroalkenes via allylic amination using the Pd catalyst. | | Synthesis | Part C: 1,1-dimethylethyl 3,3-difluoropyrrolidine-1-carboxylate (0.868 g, 4.19 mmol) was dissolved in 1.5 mL of 1,4-dioxane and cooled to 0°C. A 1,4-dioxane solution (11 mL, 44 mmol) of 4 M hydrogen chloride was slowly added with stirring. The reaction mixture was continued to be stirred at 0°C for 40 minutes, then brought to room temperature and stirred for 1 hour. Upon completion of the reaction, the solvent was removed by concentration under reduced pressure to afford 0.65 g of 3,3-difluoropyrrolidine hydrochloride (100% yield). The product was characterized by 1H-NMR (CD3OD): δ 3.54 (2H, t, J = 11.9 Hz), 3.43 (2H, t, J = 7.8 Hz), 2.40 (2H, m). | | References | [1] Patent: US2004/186134, 2004, A1.
