Versuchsvorschrift
A suspension of potassium 3-cyano-3-(3-methylphenyl)-acrylate (0.69 g, 3 mmol), in 88% formic acid (14 ml) containing concentrated sulphuric acid (2 ml) was stirred at reflux and monitored by LC-MS until the starting material was consumed. The reaction mixture was cooled to room temperature and poured into ice/water. The resulting precipitate was recovered by filtration, washed with water (15 ml), heptane (15 ml) and air dried.
