실험 절차

tert-Butyl 4-chloro-5,8-dihydropyrido[4′,3′:4,5]thieno[2,3-d]pyrimidine-7(6H)-carboxylate from Example 11A (3.24 g, 9.95 mmol) was dissolved in 2-propanol (40 mL). 3-Amino-5-chlorophenol (1.50 g, 10.4 mmol) from Example 64A and a 4 M solution of gaseous hydrogen chloride in dioxane (124 μL, 0.50 mmol) were added, and the mixture was heated to 80° C. for 20 h. Subsequently, further hydrogen chloride in dioxane (5.0 mL, 20 mmol) was added, and the mixture was heated for additional 3 h. The resulting precipitate was collected by suction filtration to yield 3.63 g (99%) of the title compound.
