실험 절차

Methyl-4,4-dimethyl-3-oxovalerate (15.8 g, 0.1 mol) and 2-methoxy-5-nitroaniline (16.8 g, 0.01 mol) were taken up in toluene (150 mL) in a round bottomed flask fitted with a Dean-Stark trap. The mixture was heated to a vigorous reflux while the MeOH side-product was distilled off and removed. After 4 hours, the mixture was cooled and the toluene removed in vacuo. The residue was recrystallized from acetonitrile to yield 27 g of the desired condensation product.
