Reaction Steps

Potassium fluoride 40 wt. % on alumina (218 mg, 3.75 mmol, 25 eq.) was added to a mixture of [2-((S)-2-acryloyl-2,3-dihydro-1H-isoindol-1-yl)-4-chloro-phenoxy]-acetic acid ethyl ester (58 mg, 0.15 mmol, 1.0 eq.) and 5-fluoro-1H-indazole (25 mg, 0.18 mmol, 1.2 eq.) in MeCN (1 mL). The resulting suspension was stirred at 80° C. for 18 hours. Formic acid was added (0.2 mL). The reaction mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified by prep. HPLC (column: Atlantis, 30×75 mm, 10 um, UV/MS, acidic conditions) and concentrated in vacuo to give the desired product as a white foam.
