실험 절차

To a stirred solution of methyl 5-(6-chloro-4-(isopropylamino)pyridin-3-yl)-1,3,4-thiadiazole-2-carboxylate (12) (60 mg, 0.1 mmol) in MeOH (2 mL), (S)-Prolinol (0.9 mmol, 5 equiv) was added and refluxed at 80° C. for 1 h. The reaction mixture was cooled and concentrated. The crude material obtained was purified by column chromatography through silica gel and MeOH: DCM as eluent to isolate the desired product, (5-(6-chloro-4-(isopropylamino)pyridin-3-yl)-1,3,4-thiadiazol-2-yl)(3-(hydroxymethyl)pyrrolidin-1-yl)methanone( ). LCMS: XBridge Phe 8, 4.6×30 mm, 3.5 μm; Solvent A=2% ACN: 98% H2O: 10 mM NH4COOH; Solvent B=98% ACN: 2% H2O: 10 mM NH4COOH; gradient 0-100% B over 1.5 min (3.2 min run time); retention time: 1.585 min; LCMS (ES-API), m/z 379.8 (M−H).
