Reaktionsschritte

Triethylamine (21 ml, 0.15 mmol) and 4-fluorobenzenesulfonyl chloride (29 mg, 0.15 mmol) were added to a solution of 1-(R)-[4-(3,4-dichlorobenzyl)piperazin-1-ylmethyl]-2-methylpropylamine (50 mg, 0.15 mmol) [prepared as described in Example 1 above] in methylene chloride (1.5 ml). The reaction mixture was stirred for 2 h, then concentrated. Purification by flash chromatography with 20:1 methylene: methanol as the eluant gave N-{1-(R)-[4-(3,4-dichlorobenzyl)piperazin-1-ylmethyl]-2-methylpropyl}-4-fluorobenzenesulfonamide (49 mg) as a solid.
