BDB / "J" Synthesis | |||||||
here is the original synthesis, but in german for 2-amino-1-(3,4-methylendioxyphenyl)-butan [upload] https://www.the-hive.ws/forum/pic_proxie.pl/bdb.pdf?read_cache=1&update_cache=1&name=8VX0dxDXVOqAa3SYOAkFKq I try to translate it in english: -to a solution of 5g (33.3 mol) of piperonal in 10 ml Nitropropan, is added 0.25 ml n-Butylamin and 0.25 ml acetic acid, - it is heated at 140C then refluxed at this temperature for 3h, -it is concentrated under 60C and 1mbar -the yielding oil is diluted under a bit heating with 7 ml Methanol -it is cooled down at -15C and filtrated at this temperature -add 3 ml methanol then heat it will be heated 50C and vakuum dried. What should be done, then it is impossible for a Ghetto-Chemist to produce 1mbar Please answer simply, and explain that non-chemist understand it[- Ne deutsche Antwort würde ich besser verstehen. |

What should be done, then it is impossible for a Ghetto-Chemist to produce 1mbar? No body knows what to do, i thought here are at least a few Chemists? Ne deutsche Antwort würde ich besser verstehen. |

there is probably a better way to do this

how to extract bdb | |||||||
Has somebody the Monography of BDB? Does somebody know how to clean it with a destilation or Acid/Base extraction? Ne deutsche Antwort würde ich besser verstehen. |

Piperonal and 1-Nitropropane method | |||||||
Shulgin writes that the Piperonal and 1-Nitropropane method gave "unsatisfactory yields". I can't find the yeild results for this method anywhere. I understand that it may give yeild results Shulgin was not happy with, but for a newbee it may be worthwhile to look into. Does anyone have the write-up for this method with results? |

Thank you very much Rhodium. | |||||||
Thank you very much Rhodium. Your knowledge never ceases to amaze me. My question now is, could one use 3,4-Methylenedioxyphenyl-2-nitro-1-butene in place of 1-(3,4-methylenedioxyphenyl)-2-butanone in the preparation of J? Also, how is the iron and acid reduction of the appropriate nitrostyrene carried out? Shulgin writes:"the Efforts to prepare this ketone (I'm assuming 1-(3,4-methylenedioxyphenyl)-2-butanone) by the iron and acid reduction of the appropriate nitrostyrene (1-(3,4-methylenedioxyphenyl)-2-nitro-1-butene, mp 64-65 °C) were thwarted by the consistently unsatisfactory yield of the precursor from the reaction between piperonal and 1-nitropropane" |

I think you need to UTFSE some more... | |||||||
My question now is, could one use 3,4-Methylenedioxyphenyl-2-nitro-1-butene in place of 1-(3,4-methylenedioxyphenyl)-2-butanone in the preparation of J? Naturally. It could be reduced by any of the numerous methods available for the reduction of nitroalkenes to amines. See for example the article I linked to in my last post or Pihkal #100 (MDA) (http://www.erowid.org/library/books_online/pihkal/pihkal100.shtml) Also, how is the iron and acid reduction of the appropriate nitrostyrene carried out? See for example the preparation of MDP2P from the nitrostyrene in Pihkal #109 (MDMA) (http://www.erowid.org/library/books_online/pihkal/pihkal109.shtml) The Hive - Clandestine Chemists Without Borders |
