Procedure

Compound 3 (3.87 g) was dissolved in toluene (50 mL) and a 2N aqueous solution of sodium hydroxide (50 mL), and tetrabutylammonium bromide (700 mg) and tosyl chloride chloride (4.10 g) were added thereto under ice cooling, followed by stirring for 30 min. To the reaction solution 1-phenyl-1H-tetrazole-5-thiol (4.60 g) was added, followed by stirring at 60° C. overnight. The reaction solution was poured into water and extracted with tert-butyl methyl ether. The organic layer was washed with saturated brine; dried with sodium sulfate; and concentrated. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1→7:3) to obtain the title compound (5.43 g) having the following physical properties:
