Procedure

60 μl (0.7 mmol) of oxalyl chloride and 5 ml of dichloromethane were introduced into a three-necked flask and under a nitrogen stream. 100 Al (1.4 mmol) of DMSO were added at -60° C. and the mixture was stirred for 10 min and then a solution of 200 mg (0.6 mmol) of 4-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydro-2-naphthylthio)benzenemethanol in 5 ml of dichloromethane and 400 μl (3 mmol) of triethylamine was added. The mixture was stirred at room temperature for one hour, the reaction medium poured into water, extracted with dichloromethane, the organic phase decanted off, dried over magnesium sulfate and evaporated.
