実験手順

tert-Butyl 6-(4-(6-amino-5-(1-(2,6-dichloro-3-fluorophenyl)ethoxy)pyridin-3-yl)-1H-pyrazol-1-yl)-2-azaspiro[3.3]heptane-2-carboxylate (53 mg, 0.094 mmol) was dissolved in formic acid (3 mL). The solution was sonicated at room temperature for 1.0 h and then concentrated by evaporation in vacuo to give the residue. Toluene (2×5 mL) was added and evaporated again. Ether (10 mL) was added and the mixture was stirred at room temperature for 1.0 h. The solid was collected by filtration, washed with ether (10 mL) and then dried under high vacuum to afford (±)-5-(1-(2-azaspiro[3.3]heptan-6-yl)-1H-pyrazol-4-yl)-3-(1-(2,6-dichloro-3-fluorophenyl)ethoxy)pyridin-2-amine formate (29 mg, 61%) as an off-white solid.
