Feasable conversion of lysergic acid amide to lysergic acid diethylamide? (LSA => LSD)

[mxtlrr_chem]

Is this even possible without low yields (< 20%)?

Low yield or not production is cheap and raw LSD is very rare and a gram in Europe after being laid on tabs is worth qtr-half a mil easy.
If it’s for personal use and recreation you’ll get enough to trip no problem. If you’re making it to sell you just have to scale.
