ethyl 2-(1,3-dioxoisoindol-2-yl)acetate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 12.4 g of 4-fluorobenzaldehyde, 31 g of phthalimidoacetic acid ethyl ester and 13 g of β-aminocrotonic acid ethyl ester in 100 ccs of ethanol are heated to the boil under reflux for 2×24 hours, the mixture is allowed to cool, whilst stirring, and, after filtering, yellow crystals of melting point 144°-145° C. (ethanol) are obtained, yield: 80%. under reflux for 2×24 hours to cool after filtering yellow crystals of melting point 144°-145° C. (ethanol) are obtained
