To a solution of (S)-1-(tetrahydrofuran-2-yl)methanol (7.95 g) in pyridine (35 ml) was added, at −15° C., methanesulfonyl chloride (7.47 g), and the reaction was stirred at 0° C. for 5 hours. After the addition of water, the mixture was extracted with ethyl acetate. The organic phases were dried over magnesium sulfate and concentrated. The product was thus obtained with the molecular weight of 180.22 (C6H12O4S); MS (ESI): 181 (M+H+). Analogously, methanesulfonic acid (R)-1-(tetrahydrofuran-2-yl)methyl ester was synthesized.
