Pharmacology - synthesis of other opiotes from mophine sulfate

[synthboy]

Swim recently had a similar post that was moved but he does not know where so he will reiterate with the knowledge he has gained from other helpful members. 'The Docta' was so kind to provide Swim with a very thorough synthesis of heroin from morphine but SWIM, and no doubt just about everyone else in the world, would have a very a difficult time acquiring the notorious acetylating agent acetic anhydride(please correct Swim if he is wrong aboug AA's availability). Swim would like to know of any other derivatives that he could homebake with his 30mg MS IRs... codeine perhaps( whose structure only has a single extra methyl group and the C14 position Swim believes). Swim knows that codeine is weaker than morphine per mg and is metabolized to morphine in vivo anyway but still wants to synth some. Please help Swim is bored with his morphine tabs.
