실험 절차

To 3-bromo-4-chloro-N-methyl-N-{2-[3-(1H-tetrazol-5-yl)-propoxy]-phenyl}-benzamide (1.90 g, 4.2 mmol) in DMF (20 mL) was added 2-(trimethylsilyl)ethoxymethyl chloride (0.89 mL, 5.1 mmol) in one portion, followed by addition of K2CO3 (1.16 g, 8.4 mmol). The mixture was stirred at room temperature for approximately 16 hrs and then was partitioned between ethyl acetate and water. The organic layer was separated, washed with water and brine, and was dried over MgSO4. The filtrate was then concentrated in vacuo and the residue purified by silica gel column chromatography (eluent: 30% ethyl acetate in hexane) to afford 3-bromo-4-chloro-N-methyl-N-(2-{3-[1-(2-trimethylsilanyl-ethoxymethyl)-1H-tetrazol-5-yl]-propoxy}-phenyl)-benzamide and 3-bromo-4-chloro-N-methyl-N-(2-{3-[2-(2-trimethylsilanyl-ethoxymethyl)-1H-tetrazol-5-yl]-propoxy}-phenyl)-benzamide as two regioisomers (upper spot: 736 mg and lower spot: 785 mg). MS [M+H]+: 582.0; tR=2.92 min. (method 1) for upper spot and MS [M+H]+: 582.0; tR=2.75 min. (method 1) for lower spot.
