Participants

Reaction Conditions

Reaction Steps

A mixture of 4-methoxybenzyl 2-[(allyloxycarbonyl)oxymethyl]-5-cyanobenzoate (3 g, 7.9 mmol) and anisole (3.5 g) was cooled to 0° C., and trifluoroacetic acid (10 ml) was added thereto. The mixture was stirred at room temperature for 15 minutes, diluted with toluene, and the solvent was distilled off under reduced pressure. The residue was subjected to chromatography on a silica gel (35 g) column (eluent; dichloromethane:ethyl acetate=1:1) to afford the title compound (1.95 g, 95% yield) as a colorless solid (mp. 81-83° C.)
