Question Reikia pagalbos 4mmc sintezės žingsnyje

[Kiteretsu_D]

Taigi, pirmiausia į kolbą įdėjau 2b4mp, tada bezeno, tada įpylus metilamino 40 % ir pradėjus maišyti megnetine maišykle, dabar neturiu šilumos šaltinio, taigi kiek laiko turėčiau maišyti be šilumos? Ir kaip sužinosiu, kad reakcija baigta? Pradžioje skystis buvo baltas, dabar jis tapo žalsvos spalvos

why did you use benzene instead of ethyl acetate or DCM?

Its all a blur, but i seem to recall refluxing at under 105c for 2 hours or something. im not confident it will even react without the application of heat. Im old and all of the synths in my head turn into one massive synthesis of an end-game drug, and its hard to remimber which procedure goesvwith which synth, so i might be mistaken but i think you need at least enough energy to kick off the reaction

You can do cold synthesis and stir for 16h at room temperature
