Not sure I get what you mean...
You cant boil DMT out of water, DMT's boiling point is over 100c.
Also, boiling basified water can be very dangerous if you use a strong base.
DMT does not crystallize well out of a complex mixture, so you cant add a base to, say, a mimosa or acacia brew and expect all/most of your DMT to crystallize neatly. It only works when you have a relatively clean DMT salt that you redissolve in water and then add the base.
If you dont want to use a non polar, you can try this:

or, you could ( theoretically) make a brew with your plant material, evap it till it's basically dry, then mix whatever is left with a base, spread this around a glass plate and let it dry, and then use water to remove the base and other non-alkaloidal impurities and your DMT should be left behind, like the freebase conversion featured in amor fati's tek:
