12. 5 in 60 mL of toluene was heated to 225 °C for 16 h in a 250 mL stainless steel autoclave, during which the pressure increased to 15 bar. After the autoclave was cooled to room temperature, it was vented and the solvent removed in vacuo. The residual solid was sublimed at 112 °C and 0.005 mmHg. After the solid was rinsed with cold pentane and dried, 2.19 g (7.37 mmol, 86%) of orange crystalline 1 was obtained, with satisfactory elemental analysis.
