3-Chloro-4-(2-pyridylmethoxy)aniline → Ethyl 4-{[3-chloro-4-(pyridin-2-ylmethoxy)phenyl]amino}-5,7-dihydro-6H-pyrrolo[3',4':4,5]thieno[2,3-d]pyrimidine-6-carboxylate

Participants

Reaction Steps

In analogy to Example 22A, ethyl 4-chloro-5,7-dihydro-6H-pyrrolo[3′,4′:4,5]thieno[2,3-d]pyrimidine-6-carboxylate from Example 21A (100 mg, 0.35 mmol) and 3-chloro-4-(pyridin-2-ylmethoxy)aniline from Example 6A (87 mg, 0.37 mmol) were reacted to the title compound to give 158 mg of a crude product (72% purity, 67% yield), which was used in the next step without further purification.
