What is the most practical way for synthesizing ethylamine for a home chemist?
Commercially it is made from ammonia and ethanol, but I'd imagine working with ammonia would be a pain in the ass.

Hydrogenation of acetonitrile, acetamide, and nitroethane affords ethylamine. These reactions can be effected stoichiometrically using lithium aluminium hydride. In another route, ethylamine can be synthesized via nucleophilic substitution of a haloethane (such as chloroethane or bromoethane) with ammonia, utilizing a strong base such as potassium hydroxide. This method affords significant amounts of byproducts, including diethylamine and triethylamine.[4]

" This route is also applicable to other nitroalkanes (eg - ethylamine from nitroethane) "

This seems like a fine procedure, unfortunately the cost of nitroethane is kinda high.
How about procedures for making ethylamine from acetonitrile and acetamide? These chemicals are much cheaper then nitroethane, and easier to acquire. I am not sure how difficult haloethanes are to acquire.
