実験手順

A mixture of 1,1-bis(2,4-dimethylphenyl)-2-(1-methyl-1H-tetrazol-5-yl)ethanol (1.8 g, 5.4 mmoles) and potassium hydrogen sulfate (100 mg) was placed in an oil bath preheated to 190° C. After 15 minutes, the melt was cooled and methylene chloride added to the residue. The insolubles were removed and the solution evaporated. The residue was crystallized from isopropyl ether to give 1.2 g of the title compound; m.p.=143°-143.5° C.
