This subject matter has been discussed repeatedly ad nauseum, and so I'm closing this and advising the OP to use the forum search engine to find info on desomorphine.
It certainly can be synthesized to a pharmaceutical grade using legitimate solvents, catalysts, reactants, hopefully no petroleum products... but anyways yes in theory it can be done but this is not the place to learn how to make desomorphine, and we don't condone it's abuse via the clearly devastating harm induced by it's abuse as demonstrated in hundreds of thousands of ex-soviet and Russian ghettos. It's cheaper than heroin, I would equate it a bit to in America, smurfing packs of pseudo and synthesizing using the idiotic, to say unstable and unsafe are understatements of the year.... Those Li strips are so fucking reactive. and if you're not venting it like every few seconds, the pressure will also cause a huge firey blast and kill you if not land you in the ICU Critical Burn Unit. whichever is worse...
Anyways, IMO meth manufacture should be left to the Fictitious Walter White's of this world, who know chemistry and do a proper full synth and reach near Desoxyn-grade, vs shake n bake which produces absolute shit low quality crank is inferior to properly mfc'd methamphetamine hydrochloride, not to condone the abuse of any of these. But just like desomorphine, the synth process in a clandestine "lab" with poor ventilation and volatile explosive liquids phase changing rapidly evaporating into gaseous form, it is so fucking dangerous, one static shock and that could be the end of your life, as you knew it. The shake and bake and desomorphine prep process are similar in that they produce highly toxic and carcinogenic, mutagenic, teratogenic, biocidal, toxic oh so toxic to humans, animals, and the local groundwater and environment. Much more waste than a proper cook, that's for DAMN sure.
