A mixture of 1-ethylpyrazole-4-carbaldehyde [0.322 g (2.6 mmol)], malonic acid [0.530 g (5.2 mmol)], pyridine (5 mL) and piperidine (0.050 mL) was stirred at 80 C. for 1 h followed by stirring for 3 h at 115 C. The reaction was then poured into water (100 mL) and acidified with conc. HCl. The resulting white ppt., product, was filtered and vacuum dried. Yield=436 mg (99%) MS (m\/z): 169 [M+H]<\/p>\n
