Computed Properties of C8H6N2O2

To a mixture of 4-bromobenzaldehyde (2; 100g, 543 mmol) and piperidine (26 mL, 260 mmol) was added 4-cyano-2-nitrotoluene (1; 92 g, 567mmol). The resulting slurry was heated at 125 C for 4 h until it became a solid. After cooling to room temperature, CH2Cl2 (200 mL) was added to the solid mass and the mixture was stirred for 30 min. To the resulting mixture was added hexane (200mL), and the suspension was stirred at room temperature overnight. The solid was filtered, washed with hexane (1 L), and dried under vacuum to provide 178 g (99 %) of product as yellow solid, which was used in the next step without further purification.
