"Red tar"[edit]

I heard 'home bake' Dipipanone is called "red tar" [1], is there something to this? (talk) 20:53, 30 October 2008 (UTC)


A friend of mine has been living in South Africa and has referred to Dipipanone as 'pinks', due to the colour of the Welconal tablets. Dealers paint their doors pink to signify the sale of the drug.

During the 80's the drug was used across the UK under the name Dicanol, given the nick name 'dykes'. —Preceding unsigned comment added by (talk) 20:13, 6 October 2009 (UTC)

Dipipanone Synthesis Incorrect[edit]

I was reading Paffit's "The Organic Chemistry of Drug Synthesis Vol. 1" the other day and saw that this drug is created by the nucleophilic attack of diphenylacetonitrile on 1-(2-Chloroethyl)piperidine, not on 2-chloro-1-dimethylamino-ethane as the article states. If i'm wrong, please don't change the article. If only 2-chloro-1-dimethylamino-ethane was used, where would the piperidine ring in dipipanone come from?

I am 95% sure that the suggested synthesis would produce normethadone, not dipipanone. Anyone with some more experience care to comment? —Preceding unsigned comment added by (talk) 09:10, 28 January 2011 (UTC)

Just a suggestion!

Synthesis Again[edit]

I didn't check the reference but the above poster is essential correct. The synthesis of methadone involves the attack of diphenylacetonitrile on 2-chloro-1-(dimethylamino)-propane. You need one more carbon for the methyl side chain near the nitrogen. For dipapanone it would be on 2-chloro-1-piperdinyl-propane. —Preceding unsigned comment added by (talk) 02:25, 22 December 2010 (UTC)
