You are posting all over the place trying to get an answer on how to crack your trimer at 250C even though it detonates at 130C. You seem to know that the final product is stable and that it has been made by others in the past. It sounds like you need to do a literature search to find your answer. My guess is that a different chemical synthesis route was used to make the final product. You also might be able to get more help if you told us exactly what trimer you are trying to crack. Many people here have vast experience but can not help you if you are being very secretive.
Good luck
