Versuchsvorschrift

tert-Butyl (2S)-2-[(1E)-3-{4-[(3-chloro-4-fluorophenyl)amino]-5,8-dihydropyrido[4′,3′:4,5]thieno[2,3-d]pyrimidin-7(6H)-yl}-3-oxoprop-1-en-1-yl]pyrrolidine-1-carboxylate from Example 14A (397 mg, 0.712 mmol) was dissolved in 2-propanol (4 mL), and a 4 M solution of gaseous hydrogen chloride in dioxane (0.36 mL) was added. The mixture was stirred for 3 h at 70° C. The solvent was then removed in vacuo. The residue was dissolved in ethyl acetate and washed with 1 N aqueous sodium hydroxide solution. The organic layer was dried over sodium sulfate, and the solvent was evaporated. The crude product was purified by preparative HPLC to yield 139 mg (42%) of the title compound.
