実験手順

200 mg (0.595 mmol) of 3-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-1,2,4-triazine-5,6-diamine were admixed with 8 ml of dichloromethane and cooled to 0° C. 545 mg (4.757 mmol) of methanesulphonyl chloride and 481 mg (4.757 mmol) of triethylamine were added and the mixture was stirred at RT for 72 h. The mixture was diluted with dichloromethane and the precipitate was filtered off with suction. The filtrate was partitioned between water and ethyl acetate. The organic phase was dried over sodium sulphate and concentrated on a rotary evaporator. The residue was purified by preparative HPLC (mobile phase: acetonitrile/water with 0.1% TFA, gradient 30:70→95:5). This gave 57 mg (18% of theory) of the target compound.
