| Reactant | (2S, 3S)-3-(5-(1,1-Difluoroethyl)-2-(trifluoromethoxy)benzyl)amino-2-phenylpiperidine | HCID 57090611 | — |
| Product | (2S,3S)-3-(5-(1,1-Difluoroethyl)-2-(trifluoromethoxy)benzyl)amino-2-phenylpiperidine dihydrochloride | HCID 86757653 | 87% |
Reaction Steps
The Compound 27 (360 mg. 0.87 mmol)was treated with methanol-hydrogen chloride (ca 20 ml) and the solvent was evaporated in vacuo to give crude product as a white solid. The crude product was recrystallized from ethanol-diethyl ether to give Compound 28 (370 mg, 87%) as a white solid.
