실험 절차

The product from Step 4 (2.1 g, 7.95 mmol) and ethyl cyanoacetate (3.6 g, 31 mmol) were heated together at 195° C. in a sealed tube for 54 minutes. After cooling to room temperature, the product crystallized and the crystals were collected and washed with ethanol to give the title compound (0.87 g, 35%). MS (ES+) m/e 313/315 [M+H]+.
