I'd need to convert l-methionone with liquid ammonia and sodium metal with the temperature of -30 to -40 Celsius. What would be the cheapest tool to use/buy. The reaction would take ca. 2.5 hours.

Another thing: What would happen if the ammonia evaporates and comes in contact with, lets say an unshielded electric cable (in the deep freezer for example)? Could that happen, or is that impossible. If not, I'd have to take a different approach (methionine with sulferic acid 125-135 Celsius to create homocystine, then reduce it somehow to get homocysteine (disconnect the di-sulphide bond).

I don't know what your purpose is, but this does not sound like a properly equipped commercial or academic lab employing proper safety precautions. I don't think we should give advice to such questions or questioners. Perhaps you could explain your legitimate purpose.

I'd like to synthesize GW274150, an INOS inhibitor. I'm not a professional chemist, but a computer scientist. The substance is to test the response in wild-type mice to a particular physiological condition.
If this synthesis coincidentally resembles something illegal, then please inform me, because I'd like to know that as well.

If you have no experience and you are not trained, that makes the synthesis a big no.

That requires permits and what not. I don't see this thread going into any acceptable direction, I am locking it.

Feel free to contact me by PM if you feel there are information that can change my mind.
