Triethylamine → 2-(2,2-Dimethyl-1,3-dioxan-5-yl)ethanol

Participants

Reaction Steps

To an acetone (30 ml) solution of the 2-(hydroxymethyl)butane-1,4-diol (3.4 g, 28.3 mmol) obtained in accordance with the method described in J. Med. Chem., 30 (9), 1636-1642 (1987), p-toluenesulfonic acid monohydrate (244 mg, 2.83 mmol) was added at room temperature and the mixture was stirred for 15 hours. To the reaction mixture, triethylamine (394 μl, 2.83 mmol) was added and the mixture was concentrated. The residue was purified by silica gel column chromatography (elution solvent: heptane/ethyl acetate) to obtain the title compound (1.0 g, yield: 22%) as a light yellow oil.
