To a solution of 5.0 g 4-(2-hydroxy-ethylsulfanyl)-phenol (29 mmol) in 100 ml CH2,Cl2 were added at 0° C. 2.6 ml pyridine (32.3 mmol) and 2.34 ml SOCl2 (32.3 mmol), dissolved in 10 ml CH2Cl2. The reaction mixture was stirred for 1 h at r.t. and then quenched by the addition of water. The organic phase was separated and washed twice with sat. NaHCO3-solution. The combined aqueous phases were extracted with CH2Cl2 twice and the combined organic layers were dried over MgSO4 and the solvent was removed under reduced pressure to give 4.6 g product (24.3 mmol, 83%) as a yellow oil.
