Reaction Steps

3- Formylaminothiophene (Bull. Soc. Chim. Fr. 1976,151) (2 g), dissolved in dry THF (20 ml), was dropped into a freshly prepared solution of lithium diisopropylamine (0.035 mol) in THF (35 ml) at −70° C. The solution was warmed to −20° C. and stirred for 30 minutes, then cooled again to −70° C., whereupon trimethylsilylchloride (5 ml) was added. After stirring for an additional hour at this temperature the mixture was slowly warmed to room temperature and stirred for 4 hours. Quenching with a saturated solution of ammonium chloride, extracting with ethyl acetate, drying over sodium sulfate, removing the solvent and applying chromatography on silica gel (hexane:ethyl acetate 2:1) yielded 2-trimethylsilyl-3-formylaminothiophene (1.2 g) (m.p. 74-76° C.).
