Reaction Steps

(Step 2) To 1-(2-tert-butoxy-2-oxoethyl) 5-tert-butyl (Z)-2-methyl-4-{(E)-2,4,6,8,10-pentamethyldodec-2-enylidene}pentanedioate (14.7 mg, 0.027 mmol) obtained in Step 1, dichloromethane (2 mL) and trifluoroacetic acid (0.2 mL, 2.6 mmol) were added, and the resulting mixture was stirred at room temperature for 24 hours. The solvent was evaporated under reduced pressure, and the resulting residue was purified by thin-layer column chromatography (methanol/chloroform=1/9), whereby Compound 9 (8.6 mg, 74%) was obtained.
