Reaction Steps

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)-thiophen-2-yl]-acetonitrile (2.67 g, 12.77 mmol) in a 1:1 mixture of MeOH and H2O (11 mL) was treated at rt with KOH (1.43 g, 25.54 mmol). After stirring at reflux for 1.5 h, the cooled reaction mixture was washed with ether. The aq. phase was carefully acidified to pH 4-5 with 1M HCl and the product was extracted several times with CH2CL2. The combined org. extracts were dried over Na2SO4, filtered, and the solvents were removed under reduced pressure to give the title compound as a brown oil. LC-MS-conditions 02: tR=0.79 min.
