Procedure
4-[6-(Benzyl-methyl-amino)-3-methyl-[1,2,4]triazolo[4,3-b]pyridazin-8-ylamino]-piperidine-1-carboxylic acid tert-butyl ester (4.08 g; 9.04 mmol) was dissolved in 20.0 ml of DCM and treated with 5.0 ml TFA. It was stirred at ambient temperature for 1 hour. The solution was concentrated under reduced pressure and the residue taken up in DCM and washed with half concentrated NaHCO3 solution. The organic phase was dried over MgSO4 and concentrated.
