Procedure
Under an atmosphere of nitrogen, 78.7 g (500 mmo)l [sic] of 4-(methylthio)benzyl alcohol were dissolved in 154.5 g of toluene. 131.6 g, (1.3 mol) of conc. HCl were added, and the mixture was stirred at 20-25° C. for 30 min. After 2 h (no starting materialleft according to TLC), the reaction mixture was diluted with 349 g of toluene and the aqueous phase was separated off. The organic phase was neutralized using 14.0 g of NaHCO and, after 15 min, filtered, and the solvent was evaporated. The residue that remained consisted of 107.4 a of a yellow oil with toluene, corresponding to a yield of >95% (according to NMR).
