Procedure

At a temperature of 0° C. to a suspension of 6.8 g (0.18 mol) of LiAlH4 in 200 ml of Et2O was slowly added 50.0 9 (0.18 mol) of (rac)-3-benzylsulfanyl-3-methyl-hexanoic acid ethyl ester of step (b) under stirring such that the temperature did not exceed 10° C. Stirring was continued for 1 h and under cooling acetone and then 400 ml of a saturated NH4Cl solution was slowly added. The reaction mixture was extracted three times with 200 ml of Et2O, the combined organic layers were dried over Na2SO4 and concentrated in vacuo and gave 40.8 g of a yellowish oil. After drying in high vacuo (0.05 mbar/150° C.) 32.5 9 (75%) of (rac)-3-benzylsulfanyl-3-methyl-hexan-1-ol in form of a yellowish oil was obtained.
