Procedimiento

Dissolved into 900 mL of acetonitrile were 226.8 g of tert-butyl 6-hydroxy-2-oxohexahydro-3,5-methano-2H-cyclopenta[b]furane-7-carboxylate (24) and 135.2 g of triethylamine. Into this mixture was gradually added 121.1 g of methacryloyl chloride at 20° C. or lower. After the resulting mixture was stirred at room temperature for 3 hours, 300 g of water was added into it and usual work-up was carried out. Recrystallization was made from ethyl acetate to give 202.2 g of the intended product (Yield 70%).
