实验步骤: Using the procedure of Step C of Example 16, 2.76 g of the product of Step A, 1.82 g of potassium carbonate, 15 ml of methyl ethyl ketone and 1.6 ml of ethyl bromoacetate were reacted. Extraction was carried out with methyl ethyl ketone and the organic phase was concentrated to dryness to obtain 3.9 g of crude product which was chromatographed on silica (eluant: hexane-ethyl acetate 8-2) to obtain 3.6 g of the expected product melting at 58° C. were reacted Extraction the organic phase was concentrated to dryness to obtain 3.9 g of crude product which was chromatographed on silica (eluant: hexane-ethyl acetate 8-2)

实验步骤: 24.2 g of 4-benzyloxy-3-methoxy benzaldehyde (Beilst. Vol. 8, II p 283) were dissolved in 100 ml of acetic acid and a mixture of 25 ml of peracetic acid and 50 ml of acetic acid was added without exceeding 45° C. The mixture was stirred for 18 hours at +40° C. and after concentration to dryness, the residue was chromatographed on silica (eluant: hexane-ethyl acetate 8-2) to obtain 9.1 g of the expected product melting at 84° C. was added without exceeding 45° C after concentration to dryness the residue was chromatographed on silica (eluant: hexane-ethyl acetate 8-2)
