Procedure

A mixture of (2-(fluoromethyl)-1,3-dioxan-2-yl)methyl benzoate (2.22 g, 8.73 mmol), methanol (20 ml) and a 1N-aqueous sodium hydroxide solution (13.1 ml) was stirred at room temperature overnight. Ammonium chloride was added to the reaction mixture, which was concentrated. The residue was suspended in tetrahydrofuran and ethyl acetate, and then magnesium sulfate was added and the mixture was stirred for 5 minutes. After NH silica gel filtration was performed, the filtrate was concentrated to obtain the title compound (1.17 g, 89.3%) as a colorless liquid.
