(3S,6R)-6-(5-amino-2-fluorophenyl)-3,5,5-trifluoro-3,6-dimethylpiperidine-2-thione (750 mg, 2.44 mmol) was dissolved in 7M ammonia in methanol (36 ml, 252 mmol). The reaction mixture was stirred in a sealed vial at 60° C. overnight. The reaction mixture was allowed to cool to room temperature and concentrated under reduced pressure to afford (3S,6R)-6-(5-amino-2-fluorophenyl)-3,5,5-trifluoro-3,6-dimethyl-3,4,5,6-tetrahydropyridin-2-amine (708 mg, 2.448 mmol, 100% yield) as a pale yellow solid that was used in the next reaction without further purification.
