Procedure: A solution of 1,2-dihydro-1-(1-naphthalenyl)-5H-tetrazole-5-thione (50.0 mg, 0.22 mmol), 2-chloro-1-(2,3-epoxypropyl)benzene (36.9 mg, 0.22 mmol) and Et3N (0.15 mL, 1.10 mmol) in MeOH (5 mL) was heated at reflux for 2 h. The mixture was concentrated under reduced pressure and the residue was purified by HPLC using a gradient of MeCN/H2O containing TFA (0.1%) (CombiPrep ODS-AQ 50×20 mm, 5μ, 120 Å). The pure fractions were concentrated to give the title compound (12 mg, 14% yield) as a colorless solid. at reflux for 2 h The mixture was concentrated under reduced pressure the residue was purified by HPLC containing TFA (0.1%) (CombiPrep ODS-AQ 50×20 mm, 5μ, 120 Å) The pure fractions were concentrated

Procedure: MCPBA (826 mg, 3.83 mmol) was added portionwise to an ice-cold solution of 2-chloro-1-allylbenzene (487 mg, 3.19 mmol) in CH2Cl2 (20 mL). The mixture was stirred at room temperature for 16 h. Aqueous 10% Na2CO3 solution (10 mL) and CH2Cl2 (100 mL) were added. The solution was successively washed with aqueous 10% Na2S2O3 (2×40 mL) and brine (40 mL), dried (MgSO4), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (hexane:EtOAc, 8:2) to give the title compound (512 mg, 95% yield). The solution was successively washed with aqueous 10% Na2S2O3 (2×40 mL) and brine (40 mL) dried (MgSO4) filtered concentrated under reduced pressure The residue was purified by flash chromatography (hexane:EtOAc, 8:2)
