N-Desmethyltriptans: One pot efficient synthesis of N-methyl-2-5- [substituted- 1H- indole-3-yl]ethanamines
Mittapelli, Vasantha,Ray, Puma Chandra,Chauhan, Yogendra Kumar,Datta, Debashish
experimental part, p. 590 - 594 (2010/01/06)
A straightforward and highly improved method to synthesize N-methyl-2-[5-[substituted-lH-indole-3-yl]ethanamines 4-6, which are the metabolites of tryptans 1-3, is reported. The significance of the process is its simplicity and efficiency in isolating the N- desmethyltriptans derivatives as a free base.
