PROCEDURE
实验过程
To a solution of 1-(4-(oxazol-2-yl)phenyl)piperidin-3-yl methanesulfonate (110 mg, 0.341 mmol) in acetonitrile (4 mL) was added tert-butyl (1R,2R)-2-aminocyclohexylcarbamate (110 mg, 0.512 mmol). The reaction was stirred in a microwave at 120° C. for 30 min. After this time, LC/MS showed two pairs of products formed. The reaction was concentrated. The residue was diluted with EtOAc and washed with water. EtOAc extracts were concentrated. The resulting residue was purified using silica gel chromatography (ISCO system) eluting with a gradient of 50-100% EtOAc/Hex to give desired product tert-butyl (1R,2R)-2-((1-(4-(oxazol-2-yl)phenyl)pyrrolidin-2-yl)methylamino)cyclohexylcarbamate and the unwanted diastereomer, tert-butyl (1R,2S)-2-((1-(4-(oxazol-2-yl)phenyl)pyrrolidin-2-yl)methylamino)cyclohexylcarbamate (156 mg total) as a white foam.
