Procedure

Using the general procedure, 4-bromochlorobenzene (192 mg, 1.0 mmol) was coupled with 4-aminomethylpiperidine (171 mg, 1.5 mmol) at 100° C. for 20 h. Purification of the crude product by column chromatography on silica gel using methanol/dichloromethane (saturated with ammonia) (1:20) as eluent afforded the desired product as a light yellow solid (134 mg, 60% yield). Rf=0.3 (methanol/dichloromethane (saturated with ammonia)=1:20).
