実験手順

3-Methoxybenzyl isothiocyanate (22 mg, 0.12 mmol) was added to a solution of 1-(RS)-[4-(3,4-dichlorobenzyl)piperazin-1-ylmethyl]-2-methylpropylamine(40 mg, 0.12 mmol) [prepared as described in Example 1 by substituting L-N-BOC-valine with DL-N-BOC-valine] in methylene chloride (1.5 ml). The reaction mixture was stirred for 2 h and then concentrated. Purification by flash chromatography with 20:1 methylene chloride: methanol as the eluant gave 1-{1-(RS)-[4-(3,4-dichlorobenzyl)piperazin-1-ylmethyl]-2-methylpropyl}-3-methoxybenzyl-2-thiourea (18 mg) as a solid.
