| Product | 1-(4-Chloro-o-tolyl)piperazine | HCID 100852 | 73% |
Reaction Steps
The title compound was prepared following the method described for the Compound 31A of Example 31 but starting from 4-chloro-2-methylaniline instead of 4-fluoro-2-methylaniline. Purification by flash chromatography (chloroform-2N ammonia in methanol 100:3 to 100:5) afforded the title compound (73%) as an oil.
