実験手順
tert-Butyl 5-amino-2-methylthio-4-(3-methoxyphenyl)-thieno[2,3-d]pyrimidine-6-carboxamide (example 1e, 1.8 g) was dissolved in dry CH2Cl2 (30 ml) and the resulting solution was cooled down to 0° C. A solution of boron tribromide (1.28 ml) in dry CH2Cl2 (30 ml) was added dropwise and the mixture was stirred overnight at room temperature. Sat. aq. NaHCO3 was added dropwise to the reaction mixture until cessation of the exothermic reaction. Thereafter, CH2Cl2 was removed from the mixture by evaporation and a large amount of EtOAc was added. The organic layer was washed with sat. aq. NaHCO3, dried (MgSO4) and concentrated in vacuo.
