Procedure

To a solution of 3-[3-(1H-tetrazol-5-yl)phenyl]-2-propenol (2.02 g) in dry dichloromethane (50 ml) was added triethylamine (1.5 ml) followed by triphenylchloromethane (2.8 g) in dry dichlormethane. The solution was stirred at room temperature for 90 minutes, washed with water (50 ml), followed by sodium bicarbonate solution (5%; 50 ml), dried over magnesium sulphate, filtered and evaporated under reduced pressure to give a pale brown viscous oil which crystallised on standing to a cream solid.
