Reaction Steps

A mixture of 2(1-methyltetrazol-5-yl)-1,1-diphenylethanol (2.15 g; 7.68 mmole) and KHSO4 (300 mg) was heated at 200° C. for 20 minutes. The cooled mixture (50° C.) was triturated with CHCl3 (50 mL) and the organic solvent was decanted from the inorganic residue. Evaporation afforded the title compound as a cream solid (1.7 g; 85%); m.p.=147°-148° C. (crystallized from EtOAc-hexane). MS (CI): m/e=263 for (M+H)+.
