Procedure
A stirred mixture of ethyl 3-methyl-2-nitrobenzoate (0.96 g) and N,N-dimethylpropionamide diethyl acetal (2.3 g) was heated at 145° C. for 36 hours. The reaction mixture was dissolved in ethyl acetate. The solution was washed with dilute hydrochloric acid and then water, dried and concentrated to dryness. The residue was purified by column chromatography on silica gel to give a pale brown syrup (0.36 g, 33%).
