実験手順

(R)-3-[(S)—Hydroxy(tetrahydropyran-4-yl)methyl]pyrrolidine-1-carboxylic acid t-butyl ester (30 mg, 0.1 mmol) was dissolved in DMF (380 μL). NaH (3.0 mg, 126 μmol) was added and the mixture was stirred at room temperature for 15 minutes. 1,2-Dichloro-3-fluorobenzene (34.7 mg, 210 μmol) was added and the mixture was stirred at 100° C. overnight. The mixture was concentrated then dissolved in 1.2M HCl in EtOH (510 μL, 610 μmol) and stirred overnight. The product was concentrated and purified by preparative HPLC to yield the title compound as a mono-TFA salt (10.8 mg, purity 100%). MS m/z: [M+H]+ calcd for C16H21Cl2NO2, 330.10. found 330.0.
