How is 1-[N'-(4-chlorophenyl)carbamimidamido]-N-(propan-2-yl)methanimidamide hydrochloride (CAS: 637-32-1) typically synthesized?

1-[N'-(4-chlorophenyl)carbamimidamido]-N-(propan-2-yl)methanimidamide hydrochloride can be synthesized through multi-step organic synthesis involving reactions such as nucleophilic substitution, amidation, and hydrolysis. Commonly, 4-chlorobenzoyl chloride is reacted with 2-propanamine to form the intermediate, which is then treated with a carbamoyl chloride to give the final product. This synthesis typically uses anhydrous conditions and suitable catalysts to enhance the reaction yield and selectivity.
