Versuchsvorschrift

Bromoacetyl chloride (2.40 ml) was added to a solution of tert-butyl 5-amino-4-(3-aminophenyl)-2-(2-thienyl)-thieno[2,3-d]pyrimidine-6-carboxamide (example 14(g), 5.0 g) and DIPEA (10.5 ml) in DCM (50 ml). After 3 h at room temperature, the mixture was diluted with DCM, washed with sat. aq. NaHCO3, dried (MgSO4) and concentrated under reduced pressure. The crude product was purified by chromatography on silica gel using heptane/EtOAc=3/2 (v/v) as eluent. A mixture of tert-butyl 5-amino-4-(3-(2-bromoacetamido)-phenyl)-2-(2-thienyl)-thieno[2,3-d]pyrimidine-6-carboxamide and tert-butyl 5-amino-4-(3-(2-chloroacetamido)-phenyl)-2-(2-thienyl)-thieno[2,3-d]pyrimidine-6-carboxamide was obtained.
