Procedure

N-(methoxymethyl)-N-(trimethylsilylmethyl)benzylamine (548 μl, 2.14 mmol) was dissolved in the dichloromethane solution of the 2-fluoromethyl-acrylic acid ethyl ester from the previous reaction and chilled to 0 C. A solution of trifluoroacetic acid (67 μl, 0.87 mmol) in dichloromethane (0.5 ml) was added slowly. The reaction mixture was allowed to warm to room temperature in two hours and directly chromatographed on silica gel. Elution with solutions of ethyl acetate in hexanes (1:5, 1:4, 1:3) obtained the title product (143 mg) as oil.
