Reaktionsschritte

Ethyl 4-chloro-5,7-dihydro-6H-pyrrolo[3′,4′:4,5]thieno[2,3-d]pyrimidine-6-carboxylate from Example 21A (250 mg, 0.88 mmol) was dissolved in 2-propanol (2 mL). 3-Chloro-4-fluoroanilin (135 mg, 0.93 mmol) and a 4 M solution of gaseous hydrogen chloride in dioxane (11 μL, 0.04 mmol) were added, and the mixture was heated to 80° C. overnight. The precipitate was collected by suction filtration to yield 419 mg of the crude product (70% purity, 83% yield), which was used in the next step without purification.
