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

Procedure: Condensation of 3-methoxy-4-hydroxy-5-isopropyl benzaldehyde with isoamyl acetoacetate in the presence of piperidine-acetic acid and benzene as the reaction medium at reflux temperature under continuous azeotropic water removal yields the title product. The reaction takes about 4 hrs for completion. The yield obtained is typically 90-95%. at reflux temperature under continuous azeotropic water removal
