Trifluoromethanesulfonic acid → N6-(2-Aminoethyl)-2-methylsulfanyl-pyrimidine-4,6-diamine trifluoromethanesulfonate

Participants

Reaction Steps

Tert-Butyl N-[2-[(6-amino-2-methylsulfanyl-pyrimidin-4-yl)amino]ethyl]carbamate (105 mg, 0.35 mmol) was dissolved in a mixture of DCM (20 ml) and trifluoromethanesulfonic acid (5 ml) and stirred at room temperature for 2 hours. The volatiles were removed under reduced pressure, the residue was taken up in THF and evaporated again to yield 182 mg of a residue that was used directly in the next step.
