How is 2,2-Difluoroethanamine (CAS: 430-67-1) typically synthesized?

2,2-Difluoroethanamine (CAS: 430-67-1) is commonly synthesized via the reaction of 2,2-difluoroethanol with ammonium hydroxide. This process takes place in the presence of a suitable catalyst, such as palladium on carbon, and proceeds with good selectivity. The yield is typically around 80-90%, depending on the reaction conditions and purification method.
