実験手順
8.7 kg of ethyl 3-(4-fluorophenyl)-3-oxopropionate, 11.7 kg of acetoamidine hydrochloride and 28.6 kg of potassium carbonate were stirred for 5 hours at about 50° C. in 34.5 kg of methanol. Insolubles were separated from the reaction mixture and washed with methanol, and the mother liquor and the washing were combined with water and neutralized with an 18% aqueous solution of hydrochloric acid. After neutralization, the crystal was ripened by stirring under reflux for 4 hours, and the precipitated crystal was isolated by centrifugation, washed with water, dried to obtain 7.4 kg of the target compound as a white crystal.
