실험 절차

To a solution of tert-butyl (1R,2S,3S,5R)-5-(3-(6-(2,6-difluorophenyl)-5-fluoropicolinamido)pyridin-4-yl)-2-hydroxy-3-methylcyclohexylcarbamate (1.0 equiv.) in pyridine (0.12 M) was added MsCl (7.0 equiv.). The capped solution was stirred for 5 minutes and then the homogeneous solution was left standing at rt for 16 hrs. The volatiles were removed in vacuo and the residue was partitioned between EtOAc and H2O. The organic layer was washed with H2O, 10% CuSO4, H2O, Na2CO3(sat), NaCl(sat), dried over MgSO4, filtered, concentrated and purified by ISCO chromatography. The Boc protected product was treated with 25% TFA/CH2Cl2 for 20 minutes at which time the volatiles were removed in vacuo and the residue was dissolved in DMSO and purified by RP-HPLC. The product fractions were lyophilized directly to yield (1S,2R,4R,6S)-2-amino-4-(3-(6-(2,6-difluorophenyl)-5-fluoropicolinamido)pyridin-4-yl)-6-methylcyclohexyl methanesulfonate in 45% yield. LC/MS (m/z)=535.2 (MH+), Rt=0.60 min.
