実験手順

tert-Butyl (3S)-3-[((3S)-1-[(3-chloro-2-methylphenyl)sulfonyl]piperidin-3-ylamino)-carbonyl]-piperidine-1-carboxylate (10.0 mg, 200 μmol) was treated with 4.0 M of hydrogen chloride in 1,4-dioxane (0.5 mL) at rt for 1 h. The volatiles were removed in-vacuo and the residue was dissolved in acetonitrile (0.8 mL) and was treated with diisopropylethylamine (20.0 μL) and acetyl chloride (5.0 μL). The crude reaction mixture was diluted with MeOH (1.3 mL) and was adjusted to a pH of 2 using TFA and was purified by prep-HPLC to give the desired product. LCMS: (M+H)+=442.1/444.1.
