OK I hope this works out right... The attached .pdf is this post THE WAY I WANTED IT TO BE.
Compound being formed: DPT. 1,5-methylene-3,7-dinitro-1,3,5,7-tetraazacyclooctane
SEE ATTACHMENT 1
Properties:
Molar Weight: 218.173g/M
VoD: Unknown.
Impact Sensitivity: Unknown.
Friction Sensitivity: Unknown.
Classification: Secondary High Explosive.
Description of Combustion: Burns with smoky flame.
Summary of Preparation:
1,5-methylene-3,7-dinitro-1,3,5,7-tetraazacyclooctane, DPT, is easily prepared by reacting formaldehyde with nitrourea. The resulting reaction mixture is then treated with sodium hydroxide, and then with ammonia solution to precipitate the DPT. The DPT is then collected by filtration, washed with water, and then vacuum dried or air-dried.
Ingredients/ Reagents:
21 grams NitroUrea
120ml 37% Formaldehyde (aqueous)
200ml NaOH soln. (95ml dH2O, 5g NaOH)
300ml 28-30% Ammonia soln.
Reaction:
SEE ATTACHMENT 2
Procedure:
Add 21 grams of nitrourea into 120 milliliters of 37% aqueous * formaldehyde while stirring the 37% formaldehyde. After addition of the nitrourea, heat the mixture to 45 Celsius while stirring until the nitrourea has been completely dissolved. As soon as the nitrourea dissolves, remove the heat source, and then allow the mixture to cool to room temperature. Afterwards, rapidly add 200 milliliters of a 5% sodium hydroxide solution while stirring the reaction mixture. After addition, stir the reaction mixture for 1 hour. Then heat the reaction mixture to 65 Celsius for 1 hour while stirring. After heating for 1 hour, remove the heat source, and allow the reaction mixture to cool to room temperature. Afterwards, slowly add 200 milliliters of 28 - 30% ammonia solution. Upon the addition of the 28 - 30% ammonia solution, the product immediately begins to precipitate. After the addition of the 28 - 30% ammonia solution, filter-off the precipitated product, and then add 100 milliliters of additional 28 - 30% ammonia solution to the filtered mixture. After which, re-filter the mixture (using the same filter as before) to recover more precipitated product (in some cases no more precipitate will form). Then wash the filtered-off precipitate with 500 milliliters of cold water, and then vacuum dry or air-dry the product. The product will weigh 11.6 grams.

Notes on Process:
The Nitrourea can be made from urea nitrate with relative ease in the home lab.
The NaOH soln. Is easily made up also.
The Formaldehyde IS available OTC.
The Ammonia is easily procured or made.
Footnotes:
* NB: I believe Nitrourea is rather sensitive to hydrolysis by water... Would the water in the AQUEOUS solution not hydrolyse it? And would heating not speed up hydrolysis? I think though the NaOH is there to hydrolyse the reaction product of the Formaldehyde and NU.
Comments:
I have not YET tried this. I hope to soon though, provided my nitrourea works out and I can get the fucking Ammonia or make it – I HATE working with ammonia BTW.
