Procedure

(±)-1-Dodecyl-α-phenyl-1H-tetrazole-5-acetic acid, ethyl ester, i.e., the compound of Example 13(c) (14 g; 0.034 mmoles) was dissolved in absolute ethanol (175 mL) and treated with sodium hydroxide pellets (2.7 g; 0.069 mmoles). The solution was stirred for 30 minutes forming a gelatinous precipitate. The solid was removed by filtration, dissolved in water, and then acidified to a pH of 1.0 using concentrated HCl. The precipitate was collected by filtration and washed with water. Yield: 8.5 g (76%), mp 50°-51° C.
