Reaction Steps
500 mg of the product obtained in Example 73 is added to a mixture containing 815 mg of methyltriphenylphosphonium bromide, 5 cm3 of dioxan and 125 mg of sodium methylate. Agitation is carried out for 16 hours at ambient temperature, 100 cm3 of an aqueous solution of ammonium chloride is added, followed by extracting with methylene chloride, drying, eliminating the solvent under reduced pressure and chromatographing the residue on silica (eluant: cyclohexane-ethyl acetate 7-3). 80 mg of expected product is obtained.
