Reaction Steps

A solution of 3-bromo-2-hydroxy-5-(1H-tetrazol-5-yl)benzaldehyde in dichloromethane (25 mL) was treated with diisopropylethylamine (1.2 mL, 6.4 mmol) and 2-methoxyethoxymethyl chloride (0.72 mL, 6.4 mmol) under a stream of nitrogen and the mixture was stirred at room temperature for 2 hours. Workup involved rotovaping off most of the dichloromethane, followed by usual extractive workup with ethyl acetate and 5% aqueous citric acid. Collection and drying of the organic extracts gave a regioisomeric mixtures of 3-bromo-2-(methoxyethoxymethoxy)-5-(1-(methoxyethoxymethyl)-1H-tetrazol-5-yl)benzaldehyde (0.93 g) as an oil.
