4-Bromocrotonic acid → 5-({7-[(2E)-4-(3-Azabicyclo[3.2.1]oct-3-yl)but-2-enoyl]-5,6,7,8-tetrahydropyrido[4',3':4,5]thieno[2,3-d]pyrimidin-4-yl}amino)-2,3-dichlorophenol

Participants

Reaction Steps

The compound was synthesized in analogy to Example 147 from 2,3-dichloro-5-(5,6,7,8-tetrahydropyrido[4′,3′:4,5]thieno[2,3-d]pyrimidin-4-ylamino)phenol hydrochloride from Example 69A (100 mg, 0.25 mmol), (2E)-4-bromobut-2-enoic acid (61 mg, 0.37 mmol) and 3-azabicyclo[3.2.1]-octane (44 mg, 0.40 mmol) to yield 25 mg (19%).
