実験手順

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), hexamethyldisilthiane (9.45 mL, 45.07 mmol) was added dropwise to a solution of NaOMe (2.51 g, 45.07 mmol) in dry DMF (40 mL) and the reaction mixture was stirred at rt for 15 min. This dark blue solution was then added to a solution of [5-(2-methyl-[1,3]dioxolan-2-yl)-furan-2-yl]-acetonitrile (3.48 g, 18.03 mmol) in DMF (30 mL) and the reaction mixture was stirred for 16 h at rt. Water (300 mL) was then added and the mixture was extracted twice with EA (300 mL). The combined org. phases were dried over MgSO4, filtered, and the solvent was removed under reduced pressure. Purification of the residue by FC (6:4 hept-EA) gave the title compound as a yellow oil. TLC: rf (6:4 hept-EA)=0.18. LC-MS-conditions 02: tR=0.74 min, [M+H]+=228.44.
