实验步骤: A mixture of N-(3-ethylphenyl)-N-methylcyanamide (520 mg, 3.3 mmol), 2,5-dichloroaniline hydrochloride (600 mg, 3 mmol), and chlorobenzene (2 mL) were combined in a dry round bottom flask equipped with a water cooled condenser under nitrogen and placed in a preheated oil bath (150-160° C.). The reaction mixture was heated for 4 hours. After cooling, the crude reaction product was purified by crystallization from chlorobenzene/diethylether. The resulting crystals were collected by filtration, washed with diethylether, and dried in a vacuum oven (40° C., 15 hours) to yield the title compound, N-(3-ethylphenyl)-N-methyl-N'-(2,5-dichlorophenyl)guanidine hydrochloride, as a white solid (760 mg, 72% yield). were combined in a dry round bottom flask equipped with a water cooled condenser under nitrogen placed in a preheated oil bath (150-160° C.) The reaction mixture was heated for 4 hours After cooling the crude reaction product was purified by crystallization from chlorobenzene/diethylether The resulting crystals were collected by filtration washed with diethylether dried in a vacuum oven (40° C., 15 hours)

反应条件: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 2,5-dichloroaniline (Aldrich, 1.5 g, 9 mmol) in methanol (10 mL) was added methanolic HCl (1M, 30 mL) at 4° C., then the reaction mixture was stirred at 25° C. for 30 minutes. The resulting solution was then evaporated and dried under vacuum to afford 1.6 g of 2,5-dichloroaniline hydrochloride (88% yield). The resulting solution was then evaporated dried under vacuum
