YieldReaction ConditionsOperation in experiment
1.04 g With acetic acid; for 5h;Reflux; General procedure: A mixture of dialkyl malonate (10 mmol), anhyd toluene (25 mL), and N,N-dimethylformamide dimethylacetal (DMFDMA) (1.6 mL, 12 mmol) was heated under reflux for 2 h, cooled, and volatile components were evaporated in vacuo. The crude enamino ester 6 was dissolved in acetic acid (30 mL), aminopyrazole 3 (1.4 g, 10 mmol) was added and the mixture was heated under reflux for 5 h. The reaction mixture was cooled to rt and the precipitate was collected by filtration and washed with ethanol (2×10 mL) to give the title compound 7. The following compounds were prepared in this manner.
