実験手順
N-(2-{[4-(2,4-dichlorophenyl)-5-(hydroxymethyl)pyrimidin-2-yl]amino}ethyl)(tert-butoxy)carboxamide (372 mg, 0.90 mmol) was dissolved in 2 mL of anhdyrous trifluoroacetic acid and stirred at room temperature for 2 h. Evaporation of the solvent afforded {2-[(2-aminoethyl)amino]-4-(2,4-dichlorophenyl)pyrimidin-5-yl}methan-1-ol, as its trifluoracetate salt, in quantitative yield.
