実験手順

To tert-butyl (S)-1-(3-fluoro-4-(trans-4-hydroxycyclohexylcarbamoyl)phenyl)ethylcarbamate (33 mg, 0.087 mmol) was added, HCl 4M in Dioxane (2 mL, 8.00 mmol) and MeOH (0.2 ml). The reaction was stirred at room temperature for 1 hour, followed by LCMS. The solvent was concentrated off to residue to give 4-((S)-1-aminoethyl)-2-fluoro-N-(trans-4-hydroxycyclohexyl)benzamide in quantitative yield (0.087 mmol) as HCl salt. LCMS m/z 281.1 (M+H)+, Rt 0.33 min.
