Reaction Steps

2.85 g of 1-(di-p-anisylmethyl)-3-ethenyl-4-p-methoxybenzyloxycarbonylmethyl-2-azetidinone was dissolved in 14 ml of tetrahydrofuran, and 7 ml of water and 2.0 g of mercury (II) acetate were added thereto, followed by stirring at 35° C. for 5 hours. 12 ml of a 1N aqueous solution of sodium hydroxide was added thereto at 0° C., and to the resulting mixture was then added dropwise a solution of 0.25 g of sodium borohydride in 1 ml of a 1N aqueous solution of sodium hydroxide. After stirring at the same temperature for 15 minutes, the reaction mixture was neutralized with a 2N hydrochloric acid aqueous solution. Diethyl ether was added thereto, followed by filtration using Celite. The filtrate was extracted with diethyl ether, and the extract was washed with a saturated aqueous solution of sodium chloride, dried over sodium sulfate and distilled off to remove the solvent, thereby to obtain 2.6 g of 1-(di-p-anisylmethyl)-3-(1-hydroxyethyl)-4-p-methoxybenzyloxycarbonylmethyl-2-azetidinone.
