2. 2
   Temperaturethe reaction was refluxed for 6 hours with argon bubbling directly in the solution

Procedure

A suspension of 1,3-bis(2,7,9-triphenyl-1,4,5,6-tetrahydropyrido[3,2-h]quinazolin-4-yl)benzene (5) (4.4 mmol) in 220 diethyleneglycol was heated until total dissolution. 1.2 g Pd/C was then slowly added, and the reaction was refluxed for 6 hours with argon bubbling directly in the solution. The reaction was then stopped, and the suspension cooled to room temperature.
