Reaction Steps

0.051 g of magnesium turnings were suspended in 10 mL of anhydrous ethanol. 0.3 mL of carbon tetrachloride and 0.32 mL of diethyl malonate were added and the resulting mixture was stirred at room temperature (with spontaneous heating) for 1 hour, then at 60° C. for 2 hours and cooled to room temperature. A solution of 0.42 g of Compound 2A in 15 mL of toluene and chloroform (5 mL) was added dropwise and the resulting mixture was stirred at room temperature for 6 hours. After overnight resting, 0.12 mL of 98% sulphuric acid and 3 mL of water were added; the precipitated inorganic salts were filtered off and the filtrate was evaporated under vacuum to dryness.
