Procedure

A solution of tert-Butyl 4-(4-(2-fluorobenzyloxy)phenyl)-4-oxobutyrate (Step B, 1.27 g, 4.2 mmol) in dichloromethane (25 ml) was treated with trifluoroacetic acid (5 ml). The reaction mixture was stirred at ambient temperature for 3 hours and concentrated in vacuo. The purification was done by flash chromatography on silica gel column (chloroform:methanol, 95:5 spiked with acetic acid) to afford the title compound as a white powder.
