Procedure
6.65 g of 4-(tetrazol-1-yl)-butyric acid ethyl ester are stirred in 42.7 ml of acetic acid, 8.1 ml of concentrated HCl and 17.2 ml of water for 3 hours at 100°. After cooling, the reaction mixture is concentrated three times each with toluene and ether under reduced pressure in a rotary evaporator. After drying under a high vacuum, the title compound is obtained.
