Participants

Reaction Steps

To an ice-cooled solution of (S)-1-(5-chloro-2-ethoxycarbonylmethoxy-phenyl)-1,3-dihydro-isoindole-2-carboxylic acid tert-butyl ester (2.16 g, 5.0 mmol, 1.0 eq.) in DCM (100 mL), 4M HCl in dioxane (25 mL) was added. The resulting solution was stirred at r.t. for 18 hours. The reaction mixture was concentrated in vacuo. To a solution of the residue and NEt3 (3.48 mL, 25 mmol, 5.0 eq.) in DCM (100 mL), acryloyl chloride (0.45 mL, 5.5 mmol, 1.1 eq.) was added. The resulting solution was stirred at r.t. for 2 hours. The reaction mixture was concentrated in vacuo. The residue was purified by flash master (column: 100 g, flow: 45 mL/min, Heptane+20% AcOEt to Heptane+70% AcOEt) to give the title compound.
