!!!addendum: why else this article? the point is that at the stage of adding dissolved alkali to MA hcl I made a mistake. namely, I added it very quickly and as you have already realized the loss of quality of the aqueous methylamine and finally the poor quality yield of 4mmc.

Bruh, you used too much of alkali
It can сreate regrouping free base to pyrazines because of instability of 4-MMC in alkaline solutions with oxygen.
Try to use an easy drawback of alkali to prevent side reactions

Also you adding NaOH directly to methylamine salt. Better to prepare alkaline water solution and make it cold. Same need to do with water solution of your salt. In that case, after reaction you will get pretty good methylamine free base
Make sure what you using enough water, because sodium chloride can replace methylamine and your gas will be gone much faster
