see my post on DMT synthesis 1 to 4,i have used this methode with sodiumcabonate and failed because i could not stir properly and everything can out of the condenser,so i used the route tryptamine 10 gram in 100 ml isopropylalcohol and 30 gram methyliodide and stir this for 12 h(see Tikhal 412) is works fine,then i used ethanolamine wich gave me a high yield,10 gram quart. ammoniumsalt gave 5.3 gram raw DMT.
