Reaction Steps

To a solution of 756 mg of Compound (30) obtained in Example 3 in 10 ml of tetrahydrofuran and 30 ml of 0.35 M phosphate buffer (pH 6.0) solution was added 6.0 g of zinc powder, and the reaction mixture was stirred for 2 hours at room temperature. After removal of the zinc powder by filtration, the filtrate was washed with ethyl acetate and the pH of the filtrate was adjusted to 5.5, then the filtrate was concentrated. The resulting residue was purified by using Diaion HP-40R column (10% isopropanol-water) to give 415 mg (71%) of (1R, 5S, 6S )-2-[1-((4R)-methoxymethyloxymethyl-1,3-thiazolin-2-yl)azetidin-3-yl]thio-6-[(R)-1-hydroxyethyl]-1-methyl-carbapen-2-em-3-carboxylic acid [Compound (31)].
