Versuchsvorschrift

To a solution of 7-(pyridin-4-yl)thieno[3,2-d]pyridazin-4(5H)-one (100 mg, 0.44 mmol) from example 2.3, 2-quinolin-2-yl-ethanol from example a1 (83 mg, 0.48 mmol) and PPh3 (343 mg, 1.31 mmol) in DCM (10 mL), DEAD (228 mg, 1.31 mmol) was added dropwise. The mixture stirred at room temperature for 3 h, concentrated and the purified by Prep-HPLC to give the title compound as a white solid (20 mg, 11.8% yield).
