Procedure

To a solution of 2-trichloroacetyl pyrrole (1.0 equivalent, 4.67 g, 22 mmol) in methylene chloride (5 mL) was added 3-methoxypropionyl chloride (1.0 equivalent, 22 mmol) then aluminium trichloride (1.0 equivalent, 2.93 g, 22 mmol) was added in small portions. After 2.5 hours, the crude mixture was chromatographed on silica gel (MeOH 2% in DCM) to afford 3.0 g of the Friedel-Craft product. 1H NMR consistent with structure.
