I assume there is little danger of a reaction getting out of
hand but just want to be sure.

If your reaction is not sufficiently exothermic to necessitate cooling
at some scale of reaction then your reaction is not likely to proceed
spontaneously. The only endothermic reaction that proceed
spontaneously are entropically driven by some sort of phase change. Do
you have much experience with chemical reactions to warrant a chemical
engineering pint of view? Start with small reaction size first and
learn from your mistakes

Thanks for the info. It sounds from the procedure that one just mixes
and heats. Prolly ok on a lab scale. If it works of course scaleup is
a consideration along with price. Just trying to anticipate problems
in advance. There is also a procedure that might work which involves
heating the anhydrous arylamine hydrochloride with ethanol at elevated
temperatures, but this might limit your choice of an outside source
since not very may places have the equipment to do this on a large
scale.
