Reaction Steps

200 mg (purity 67%, 0.398 mmol) of 3-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-1,2,4-triazine-5,6-diamine were admixed with 4 ml of dichloromethane and cooled to 0° C. 151 mg (1.594 mmol) of methyl chloroformate dissolved in 1 ml of dichloromethane and 161 mg (1.594 mmol) of triethylamine were added and the mixture was stirred at RT for 15 min. The precipitate was filtered off with suction and dried under high vacuum. This gave 97 mg (61% of theory) of the target compound.
