US patent 7045545
Eli Lilly and Co
Aminoalkylbenzofurans as serotonin (5-HT(2c)) agonists
Please don't confuse a personal experience with an overarching statement concerning a drug you may or indeed may not have ever taken, depending on how dishonsest the dealer is.
ALL of the MAPB drugs were produced as the result of poor communication. The Israeli chemist asked in a manner that had to be understandable to the Chinese manufacturers. He included a statement on reduction (actually reductive amination) and the Chinese took this to mean the reduction of the benzofuran system to the matching dihydrobenzofuran.
A sample was sent to the Dutch guy who did the marketing who said he liked it but wasn't... THAT impressed.
The error was tracked down but since they now had 4 products instead of 1, they sold them all. When the primary amine was banned, they made the N-methyl, when that was banned the N-ethyl.
By now, the 2 guys who sold this class of compound as 'Benzo-Fury' are out of the picture. Chinese companies offer the drug as a price lower than Benzo-Fury could obtain it for.
