By eye. Replacement of the inspired fragment, bearing primary chloride, with other possibility of a semi/covalent inhibition of the enzyme. Substitution with a carbamate (like e.g. physostigmine and Acetylcholinesterase inhibitors).
Simple and easy chemical synthesis, most of building blocks are commercially available
