実験手順

A solution of 1-(4-pyridinyl)-4-piperidinecarboxylic acid (102 mg) and HOBt (153 mg) in DMF (25 ml) was combined with WSC (192 mg) at 0° C. and stirred at 0° C. for 1 hour. The reaction mixture was combined with 1-amino-4-(6-chloronaphthalene-2-sulfonyl)-2-piperazinone (170 mg) obtained in Example 3 and stirred at room temperature for 2 days. The reaction mixture was concentrated and the residue obtained was partitioned between dichloromethane and aqueous sodium bicarbonate, and the organic phase was washed with saturated aqueous sodium bicarbonate, dried and concentrated to obtain a residue, which was purified by a column chromatography on a basic silica gel (dichloromethane to dichloromethane: methanol=20:1) and crystallized from ethyl acetate/methanol to obtain the title compound (115 mg) as a white powder.
