How is 3,3-Difluorocyclohexanamine (CAS: 921753-34-6) typically synthesized?

3,3-Difluorocyclohexanamine can be synthesized via the reduction of 3,3-difluorocyclohexanone with a suitable reducing agent such as sodium borohydride. The reaction is typically carried out in an aprotic solvent like tetrahydrofuran (THF) at room temperature. The yield is around 80% and the reaction is selective, producing the desired amine product with minimal side products.
