Procedure

A mixture of 1.3 g of Compound 31-2b, 2.0 g of 5-chloromethyl-N-triphenylmethyltetrazole, 0.6 g of sodium iodide, 0.2 g of sodium hydride (60% oily) and 50 ml of DMF was stirred at 80° C. for 15 hours. The solvent was distilled off under reduced pressure, and the residue was diluted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium bicarbonate and a saturated aqueous solution of sodium chloride, and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography [eluent: hexane/ethyl acetate (10/1)] to give 1.05 g of an oily substance containing the desired compound.
