실험 절차

Di-tert-butyl (3-(2-(4-(cyano(pyridin-2-yl)methylene)piperidin-1-yl)-2-oxoacetyl)-4-methoxy-7-(3-methyl-1H-1,2,4-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-1-yl)methyl phosphate (IIe) was dissolved in 8 ml of a mixed solution of TFA and dichloromethane (10% TFA/CH2Cl2) and the mixture was stirred for three hours. All the solvents were removed under vacuum and the residue was purified using a Shimadzu automated preparative HPLC System to give 25 mg of tert-butyl (3-(2-(4-(cyano(pyridin-2-yl)methylene)piperidin-1-yl)-2-oxoacetyl)-4-methoxy-7-(3-methyl-1H-1,2,4-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-1-yl)methyl hydrogen phosphate (II′e) and 33 mg of (3-(2-(4-(cyano(pyridin-2-yl)methylene)piperidin-1-yl)-2-oxoacetyl)-4-methoxy-7-(3-methyl-1H-1,2,4-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-1-yl)methyl dihydrogen phosphate (Ie).
