Versuchsvorschrift

A solution of 120 mg [6-(4-methoxymethoxy-phenyl)-3-methyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridin-4-yl]-methanol and 44 mg of triethylamine in 4 ml of dry dichloromethane was cooled to 0° C. and 47 mg of methanesulfonyl chloride were added. The reaction was brought to room temperature, dichloromethane and water were added and the phasese were separated. The aqueous phase was extracted with dichloromethane. The combined organic phases were dried over sodium sulphate, filtrated and concentrated. 170 mg (quant.) of the crude product were obtained as a yellow solid, which was used without further purification.
