Procedure

To a solution of this phenyl carbamate (188 mg, 0.59 mmol) in toluene (3 ml) were added triethylamine (72 mg, 0.71 mmol) and 3-[4-(2-heptylaminoethyl)piperazin-1-yl]propanol (168 mg, 0.59 mmol) and the mixture was stirred at 80° C. for 3 hours. The reaction solution was diluted with water and extracted with chloroform. The organic layer was washed with water and a saturated sodium chloride solution successively, dried over anhydrous sodium sulfate and concentrated in vacuo. The resulting residue was purified by a silica gel column chromatography (silica gel 15 g, developing solvent; chloroform:methanol=40:1 10:1) to provide 249 mg (yield 83%) of N′-[2,4-bis(methylthio)-6-methyl-3-pyridyl]-N-heptyl-N-[2-[4-(3-hydroxypropyl)piperazin-1-yl]ethyl]urea as colorless oil.
