Hydrochloric Acid → 3-Benzyloxymethyl-3-benzylthiomethylhexan-2-ol

Participants

Reaction Steps

Methyl magnesium iodide (4.0 ml, 3M solution in ether) was added to a solution of 2-benzyloxymethyl-2-benzylthiomethyl-pentanal (2.6 g.) in dry diethyl ether (50 ml.) at 0°. The mixture was refluxed, with stirring for 2 hours. The mixture was cooled and poured into 1N hydrochloric acid in ice. The aqueous mixture was extracted with diethyl ether. The ethereal extracts were washed with water, dried over anhydrous magnesium sulphate and evaporated in vacuo. The residue was chromatographed on silica, eluting with diethyl ether. 3-Benzyloxymethyl-3-benzylthiomethylhexan-2-ol was obtained as a colourless oil (0.7 g.).
