yes, stick with chinese google patent provided by me in this topic, you just have to add 20% reaction time to these numbers :).
Indian synth is bullshit, it will not provide nordiazepam.
" it is practically insoluble in water (1 g in 333 mL water), but soluble in alcohol (1 g in 16 mL). Diazepam melts between 131°C and 135°C. Diazepam injection USP is a sterile solution of diazepam in a suitable medium."
use 1:1 ratio, 1 ml of water in room temperature 210-240 mg of mephedrone. It will look like oil but dont worry about ir or colors, they will stay in water.
Keep in mind, cathiones are destroyed in neutral solutions -...
Just go with akabori momotani on small scale (https://pubmed.ncbi.nlm.nih.gov/28658566/ use scihub on google to view its safe).
After synth just seperate isomer u need with tataric acid and u are good to go with your loved route or sell to random crook.
Experience yes, but its pain in the ass (nitrogen gas, urotropine etc.) and its better to find raw (which is hard, china deathrow/india big fines). Just ask your questions and i will try to clarify.

Tldr use akabori-momotani method (benzaldehyde, dmso, n methylalanine - cheap, not monitored - scale up to 1 kg) which is used in Australia
Great video, before synth on your own boys u should read this patent (almost all questions are answered) https://patents.google.com/patent/WO2017211129A1/en
Sorry guys, this synth will not produce first compound. https://www.researchgate.net/publication/371639182_Compounds_identified_in_an_illicit_generic_Xanax_tablet_are_the_result_of_a_failed_synthesis_of_alprazolam
If u want just diazepam - erowid, last synth is fine...
