Procedure

To an ice-cooled solution of (2E)-3-[1-ethyl-6-(methoxymethyl)-4-(5-methyl-3-pyridinyl)-1H-pyrazolo[3,4-b]pyridin-5-yl]-2-propen-1-ol (44 mg) and diisopropylethylamine (20 mg) in DCM (1 ml) was added methyl chloroformate (13.5 mg) and stirred for 2 hours at room temperature. The solvent was dried up and the residue was purified with silica gel column chromatography (CHCl3-MeOH 0-2%). (2E)-3-[1-Ethyl-6-(methoxymethyl)-4-(5-methyl-3-pyridyl)-1H-pyrazolo[3,4-b]pyridin-5-yl]-2-propen-1-yl methyl carbonate was obtained as a clear oil.
