For those who is interested. I've tried this route. Overall I can confirm it works, except reaction conditions. Temperature and timing were not even close as it's stated in video. Though, in the video they use Iodo-ketone. That's a significant difference.
So, the test run I got 50g of bromine substituted 4-MPF. That was dissolved in 250ml of ethylacetate

than 100ml of aq. 38% methylamine was added. and left to stir at room temp:

After about 30min. not much had changed:

At this moment I decided to heat things up . Not higher about 50-55C.

One hour later:

It was showing some movement. And was left for another hour.
Then basically the steps were the same as in video. Ethylacetate layer with freebase was separated, washed with water, HCL added dropwise until slightly acidic pH. Then acetone poured and filtered.

And that gave raw product. Rather nice at first sight, but should be further purified, of course.

What is the final effect of your product?
I also think that 100 grams of 2-bromo-4'-methylpropiophenone is added to 400 ml of ethyl acetate,Then add 40% aqueous solution of methylamine,It is impossible to react successfully within 20 minutes.
The reaction should be successful at 40℃ for 2 hours
What do you think?

30 mins but acidification issues using ethyl Acetate. Dcm is the easiest
