Procedure

6-Fluoro-3,4-dihydro-2-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)-2H-chromene (40 mg, 0.16 mmol, diastereomeric ratio 75:25) was dissolved in acetic acid (2 ml) and demi water (0.7 ml). The reaction mixture was stirred vigorously and heated to 65° C. After 3 h at 65° C. the reaction mixture was cooled to 25° C. The solution was then concentrated in vacuo at 35° C. to obtain (R)-1-(6-fluoro-3,4-dihydro-2H-chromen-2-yl)-ethane-1,2-diol as a vetrous oil (89% yield, diastereomeric ratio 73:27).
