Versuchsvorschrift

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of [5-(2-methyl-[1,3]dioxolan-2-yl)-furan-2-yl]-methanol (3.50 g, 19.00 mmol) in dry CH2Cl2 (35.0 mL) was treated at 0° C. with Et3N (3.44 mL, 22.80 mmol) followed by DMAP (232 mg, 1.90 mmol) and Ms-C1 (1.77 mL, 22.80 mmol). After stirring at rt for 2 h, the reaction mixture was quenched with water (40 mL), extracted with CH2Cl2 (40 mL) and the combined org. extracts were dried over MgSO4, filtered, and the solvents were removed under reduced. Purification of the residue by FC (8:2:0.1 hept-EA-Et3N) gave the title compound as a yellow oil: TLC:rf (4:1 hept-EA)=0.35.
